MSFS simconnect broken, maybe, AFCBridge Failure, others

I thought at first my issue was just AFCBridge for the honeycomb throttle quadrant, it errors with AFCBridge Failed to Initialize SimConnectToTheLine

Running it manually, after loaded, same error.

Voltanta says cant connect to the sim, other apps also say this, a few do work though, strangely (maybe not using simconnect?)

I have the latest fsuipc… i’ve reinstalled (uninstalled/reinstalled msfs), started with the fresh localcache folder etc too.

This os may be buggered… i did a new motherboard, things were ok, then i had to do a system restore before that point, so i reinstalled drivers and did all that again, then later just today reinstalled msfs to get around this simconnect issue.

I have a clean community folder and base scenery only to troubleshoot.
Out of ideas short of starting with a fresh re-install of windows, but that seems extreme.

The simconnect file is using defaults, :

<SimConnect.Comm>
Static IP4 port
IPv4
local
500
64
41088
</SimConnect.Comm>

The dynamic one is port 0.
I want to say this had 127.0.0.1 before i wiped it though, on one of the lines.

Anyone have any thoughts of things to try or maybe a confirmed app to test that definitely uses simconnect to test?

update, so i found the simconnect client in add/remove in win11, i tried doing a modify but nothing ‘appeared’ to happen

I also removed simconnect.cfg from the my documents folder root area

Restarted msfs and things are working again, so i know it was one of these two solutions, maybe the modify did in fact repair behind the scenes, unsure.

Moved from User Support Hub Install, Performance & Graphics to Discussion Hub Tools & Utilities as the discussion is about connectivity to 3rd-party products and applications

Sorry for the late reply - just seen this…

Your issue could have been caused by FSUIPC., especially if it takes a long time to load MSFS to the main menu. As of FSUIPC version 7.4.12, FSUIPC has an auto-tuning of start-up parameters. When this version initially runs, default parameters are used that can cause too many failed SimConnect connection attempts and thus starve SimConnect of available connections. FSUIPC will auto-tune these parameters, but you may need to exit MSFS and restart it after the initial start for these parameters to take effect, and to reset the number of SimConnect connections used.

This is documented in the user guide, with more details in the Advanced User guide, and also in this FAQ entry: FSUIPC7: configuring connection parameters for optimal use and to prevent SimConnect issues - FAQ - The simFlight Network Forums

Please use the FSUIPC7 support forum if you have any other issues: FSUIPC7 MSFS - The simFlight Network Forums
