Game Won't Load?

[H60MTI]

Just updated to the latest version this morning and now it won't even load. I get the main home screen with the MIG-29 on it. Hit launch. I get the NVIDIA splash screen and the DCS splash screen and then nothing. The LOG stops at ASYNCNET request for dcs logout failed. No clue what that means. I attached it down below...Any insight would be great. Thanks!

Just tried a slow repair and still nothing...

So, 2 slow repairs, a fast repair, and a cleanup............And still nothing. Can't even get into the game.

You have a large number of mods, some with errors. Can you remove these and run the repair again. Can you additionally rename Saved Games\DCS to Saved Games\DCS.old and start DCS again. Whilst this is not guaranteed to resolve the issue at least it rules out any issues with potential corruption in Saved Games\DCS.

Looks like you're also running DCS from the bin-mt folder. Can you instead use the one in the bin folder. Both executables are identical and use multithreading, the bin-mt folder will be removed in the future.

Can you also confirm whether or not you are running any VPN software. Have any firewall changes been made? The error in the log appears to be network related.

If not currently using a VPN then can you please try with one.

For me DCS crashed on startup with new Geforce game ready driver Version: 581.29. Had to go back to 581.08 to fix it.

No VPNs, never had one. Anyone know a good free VPN? 

 

No firewall changes that I have made. Windows 11 might have in the background, but I haven't

 

I was unaware that multithreading is just part of DCS now versus having to go find it.

 

So, I removed some files causing the sound errors, ran the none MT executable to start, and dropped all the firewalls and still the same thing. ASYNCNET request denied and logout failed.

Don't know if anyone is still reading this...Just updated to 2.9.20.15384 and I still can't get the game to load. Still has the same HTTP request failure error. Is anyone from ED able to see this and provide some guidance or a solution? Had zero issues until these 2 updates and don't even know where to start with HTTP request.

 

Is there a way to go back in version of DCS?

[Art-J]

Yes there is, following this guide...

https://forum.dcs.world/topic/94816-guide-info-dcs-updater-usage-version-numbers-module-ids/

... but it's a desperate last resort solution in my opinion.

Have you tried temporary renaming/removal of your Saved Games/DCS folder as Sleighzy asked you to do? Repair and cleanup doesn't affect this one, so we have to figure out first if there's something hidden over there which might be causing problems.

i'm agree with @Art-J , since it doesn't look you already did. try to rename your DCS folder inside saved games to start from scrath all the setting
