msfs-2024

Hello everyone,

I’m facing a persistent issue when trying to start Microsoft Flight Simulator 2024.
Right after launching the sim, I get the following error message (screenshot attached):

English translation of the error message:

Error – Server problem detected
“It is attempting to establish a connection to the servers…
We have detected a problem with one or more essential services, which is why Microsoft Flight Simulator 2024 is currently not available.
If the problem persists, scan the QR code or visit the support page.”
Error code: 003-2001-80070525

What I have already tried:

  1. Xbox App: logged out → logged in again

  2. Microsoft Store: logged out → logged in again

  3. Restarted both Gaming Services in Windows services

  4. Deleted all XBL-related entries in Windows Credential Manager

  5. Checked Xbox Live status (all green, no outages)

  6. Restarted PC multiple times

  7. Stable internet connection (fiber)

  8. No VPN, no proxy

Despite all this, the sim always stops at this error during startup and never connects.

Question

Is this a known issue?
Does anyone have a fix for this error code or additional steps to reinitialize the server/authentication connection?

Any help is appreciated!

Please check your hosts file for entries pointing to MS Servers. Maybe some tools have cretated inappropriate entries.

I just wanted to thank you! Your hint about checking the hosts file solved the issue immediately.
Some old 127.0.0.1 entries were blocking essential services.
After cleaning them up and rebooting, MSFS started without any problems.

Really appreciate your help!

Best regards

I am having the same issue right now, but I don’t have anything in my hosts file, as I just got a new PC on Thursday.

Had no issues on using the sim Thursday and Friday, but today it comes up the the same error code the thread opener posted.

All logged in - stable connection, no issues besides the sim. Tried logging out and in again, no success.

EDIT: Looks like a simple system-reboot solved it now. :smiley:

Something changed the HOST file and after deleting the entry, everything worked again.

P.S. i dont have any clue about PS5, sorry

I do have the same issue right now.

Hy hosts file is empty. This is not the solution for me.
Any further hints?

EDIT: Did fix itself after about 1h and several reboots. Strange

I have the same issue, anyone else experience it ?

12

I am having exactly the same error. Can you help tellimg me how did you solve the problem?

13

Actually I reached the solution: change the system locale for the correct for my country

Almost same (Error 003-2000-80070057) problem here for 2 days now. Zendesk ticket posted. Hosts file is clean. Nothing really helps. Some backend server token thingy needs a reset? Have no clue at all.

I've been having this same error for 5 days now. I've already contacted Microsoft and they've done everything they could on my system, but nothing has worked. Now all I can do is wait :(

Were you able to solve it?

Well a solution, you can not call it a solution, rather a desperate attempt to fly again. What I did is to make another Windows account with admin rights. You can start MSFS there without re-installing. That worked but man what a monster job that was. Eventually you will have to migrate all your stuff to the new account. Or leave as be but that it rather cumbersome. Zendesk hasn’t been able to provide me with a solution yet. If they do I will post that here for sure. I wish you a lot of wisdom on this one. If you find something please do share.
