Sim does not start after SU8

[Xethless]

I Fixed it! I played around with Rolling cache and Google Maps Add on. now it is working

[PintsizeAsp3996]

I have the MS Store version.
MSFS 2020 will not load after SU 8.
Have uninstalled/reinstalled 5 times.
Have reinstalled Win 11.
Have tried every “trick” from this and other forums.
The program will not work.

Before trying uninstall/reinstall of MSFS 2020 I reset MS Store, reset XBox app, uninstalled/reinstalled Gaming Services, restarted all. Made sure the community folder was empty and that I didn’t have any third party files installing with MSFS 2020 so it was a “vanilla” install.
Downloaded MSFS 2020 via XBox.
Finally uninstalled MSFS 2020, then refreshed WIN 11 via a clean install from USB thumb drive.
Re-started MS Store, restarted XBox app, reinstalled MSFS 2020.
Reinstall took over 5 hours even though I have Gigabit FIOS hardwired from router to computer.
Game started. I closed the game and attempted another start (becausee I’d seen this before, game loaded, then crashed, then would not restart) and game would not load past the same screens showed in the first post on this thread.
I’ve had a copy of Flight Simulator on various computers since MS started the game nearly 30 years ago.
Had been pretty happy with the game until SU 8.
Thanks

Here are a few things to consider:

Did you ever have the Google Map replacement mod installed?
When you uninstalled the sim, did you delete any remaining folders that were left behind?
All Window’s and MS Store updates installed?
Uninstall/reinstall graphics card drivers?
Uninstall any third party antivirus?
Ensure open path through Window’s firewall?
Date,Time and Location on PC correct?
Try with a Free VPN to confirm no ISP issues?

[PintsizeAsp3996]

Answers in Parens ().

Did you ever have the Google Map replacement mod installed? (No)
When you uninstalled the sim, did you delete any remaining folders that were left behind? (As many as I could find, unless they are “hidden” files somewhere MS has not identified to users.)
All Window’s and MS Store updates installed? (Yes)
Uninstall/reinstall graphics card drivers? (Yes)
Uninstall any third party antivirus? (Only have Win 11 antivirus installed)
Ensure open path through Window’s firewall? (Not sure, MSFS worked before SU 8 without firewall tweaks. What did MS change that now requires me to change firewall settings?)
Date,Time and Location on PC correct? (Yes, and ensured proper language pack installed)
Try with a Free VPN to confirm no ISP issues? (No, was not an issue before SU 8. What changes in SU 8 require VPN?)

[TheSevenflyer]

Answer to firewall: Check and ensure, who knows what Window’s may have done.

Answer to free VPN: Same as above. There are numerous posts in here where this has fixed similar issues, none of the posters believed it could have helped prior to trying.

I suggest “workarounds” based on my experience here in the forums, it is quite extensive.
I don’t have your PC here to try by myself, and I have no idea what may or may not work to fix the issue.
In your case where you have tried a lot, these are things I noticed you hadn’t mentioned.
All I can do is suggest, in this case, things I know from experience have caused/solved this exact issue. If you don’t want to try, it is your sim!
Again, These suggestions may or may not work. All cases seem to be different.

[PintsizeAsp3996]

OK, thanks.

Changes to Firewall - can you point to the recommendation posts please?
Same for a VPN.

REgards.

[TheSevenflyer]

For firewall check do this:

In the Windows Search Bar type in Control Panel and click on it
Click on “Windows Defender Firewall”
Click on “Allow an app or feature through Windows Defender Firewall”
Click the “Change settings” button
Look for the following apps in the list:
Microsoft Flight Simulator
Microsoft Store
make sure each app has 3 ticks, 1 to the left of its name, 1 in the Private column, 1 in the Public column
Click OK
Click the X to close off “Windows Defender Firewall”

Servers Offline January 30, 2022 - Having to Use a VPN to Connect to any Online Functionality

I don’t want to advertise VPNs, but as I said in my opener, I used a VPN and the issue was gone. I could even turn the VPN off totally once I was connected and the sim did not just boot me out again. So by all means, go get yourself a free VPN or use the one you are subscribed to and give it a go if you’re struggling.

Wi-fi internet problem with the Game

The data you have provided, specs of your router and speedtest, is not enough to determine whether wifi is at play here. Best is to use an app such as Inssider on PC or Wifiman on mobile, to measure wifi signal quality where your PC is located. You can also ping your router, to determine if there is any loss. I have experienced the same error messages as you, using a Gigabit wired connection to my router. It was likely due to a slow CDN node, server side. One way to circumvent that is to…

What did you do in MSFS today? (Part 1)

I have 200 Mb/s fiber optics. It’s not a local issue. It’s a MS / Azure issue. I found a solution: connected via a free VPN to USA servers, immediately got 100 Mb/s download speeds. MS keeps on gaslighting us that slow download speeds are a user problem, but it actually is an Azure bandwidth allocation problem.

Slow Download Speed Megathread

This is the problem I have. I live in the US. Paid over $100 for this game. Steam says I have played the game 71 Hours. But all but 3 of those hours have been spent trying to download updates. I got the game running last week by going to settings and setting bandwidth to unlimited. I then downloaded, not fast, but faster. After that download was finally done I set the limit again and was able to run the game for 3 hours. And now there is another update. Don’t get me wrong. I am all for updates…

Azure AI and Netgear Nighthawk Router

I agree with the above recommendation. Investigate Bufferbloat and use QOS to improve it. Another suggestion: I found that using a VPN improved the experience. Has to do with CDNs I think. Depends on where you’re located, so YMMV. Some routers can be set up to connect to a VPN, I believe Nighthawk does. I don’t know how well it performs, encryption is a bit cpu hungry. You can try to set it up with ProtonVPN free tier, and see if it helps.

[PintsizeAsp3996]

Thanks all.
My Firewall settings were all correct, all boxes checked for both MSFS and MS Store.

As for VPN use, my PC directly connected to router via ethernet, and router is directly connected via ethernet to FIOS ONT. I get 950 GBs routinely on the PC and had 6, 7 ms ping times to the east coast MS servers when the game was playable. Agree that Azure likely severely limits access as, when the game did work prior to SU 8, I routinely got the “not enough bandwidth” warning.
So, will give the VPN thing a try.
But, the game still not playable now.

[PintsizeAsp3996]

So, basically reformatted drive C: and performed complete fresh install of WIN 11 and took computer to “new” state.
Added bare minimum programs to the drive, refreshed MS Store, reloaded Store related Apps, restarted a reset XBox then downloaded MSFS 2020 in “vanilla” state.
The thing still will not run.
Time for a refund from MS and wait for X Plane 12 I guess.

[TRPara]

Same thing here. I have been running fs2020 since day one. I have thousands invested in this game.
Never had a single problem until SU8. When SU7 was still out I tried the beta SU8. It would never run. I could always revert to SU7 and things worked perfectly. Tried the beta several times. The problem was in the beta SU8. After the forced SU8 by microsoft the game will not run. I have been able to play it by disconnecting the wifi and ethernet cable.. So I am offline. The game boots up fine and there are no problems. Plug in the ethernet and no boot. I opened a ticket with the zendesk. So far they have done nothing but give me the run around. They have wasted many hours of my free time with their guesses. I too an fed up with the B.S.
Not much I can do at this point..
I have to wonder if this wasn’t caused by MS/Asobo in an attempt to stop the google map add-on..
Anyway I doubt you will find any real help on this forum.

[TRPara]

I can get the game to play by doing to following.
1 run the game in the off line mode. (unplug ethernet and turn off your wifi).
or
2 Plug in the ethernet cable until the blue bar ends on the right side.
Unplug the ethernet cable.
wait until the welcome screen appears. ( the lower right market place will be grayed out).
Plug in the ethernet cable . After a minute the market place should light up.
Click on the world map and select your aircraft.
Click on your departure location.
On my system everything seems to load ok.
Photogrammetry is working.
If you switch menus and it stalls out on you try unplugging the ethernet cable to see if it clears the stall.
And yes the VPN thing is another waste of time.
My ping times to the East coast is 15ms. with the VPN it goes to 230 ms…

[TheSevenflyer]

I would hardly call it a waste of time, speed is going to depend on the VPN you choose.
If you didn’t notice those posted above, there are many other posts in here from folks who successfully use a VPN.

Hi, i found a solution:

My problem was that the Sim get stuck when i press “fly now”, and then started to load forever.
Before that i have notice that when i pick an airport, the map don´t load enterely whit the roads and other details of the Bing map´s. So i started to think that the problem is related whit the maps.
Over a week or so, i install the Google map replacement, and everything works fine until SU8.
So, i proceed to unnistall the GMR and erease the 2 lines wrote on my HOST file: C:\windows\system32\drivers\etc\hosts

After that i reload the sim and everything works great again.
I hope my case helps to other people!.
Happy landings!!

Thanks for the tip.
Was travelling this week so just tried it, and it worked.
Would be interesting to know why an active internet connection causes the program to hang. The “5Ws” on this would be interesting to know.
Funny that an application that touts connection/usage of data from Azure Web Services has to be disconnected from the internet to load and run.
Thanks again for the assist.

[TRPara]

I finally found the solution for my system. Not what I wanted but I can now at least run the sim without a problem. I enabled wifi on my computer and disconnected ethernet. That solved all the hang-ups. So no more wired connection. My guess (at best a guess) is it is something in the router. I am on fiber optics (Fioptics) and the router is a ZyXel…

[Libero29]

My problem is, for the first time ever, that with a photogrammetry on the FPS drops instantanelly to 1FPS and the sim, after pressing “Fly now”. With a photogrammetry off everything is normal and super fast. I tried a lot of things but without any succes. With a photogrammetry ON, the sim is unflyable.
