Epic Games Launcher crashes on MacOS due to invalid backend

PabloAtZozo · April 22, 2024, 2:53pm

Hello,

I installed v16.3.0 from Epic website. I start it the first time and the update seem to run correctly, but after that every single time it crashes with the message:

Invalid backend requested! Exiting.

I tried to delete the app (include cache) and reinstall but that did not solve the issues.
The logs reference an issue with the connection to Epic servers, so that may be related.
I’m based in Japan in case that’s important.

The log shows many instances of image files not being loadable, but these are inside the app package. Also there is a mentioned of some .ini not being set:

[2024.04.22-08.35.36:961][  0]LogEOSAuthService: Error: Consuming Client id not set! Set ConsumingClientId in EpicOnlineServices section of PortalRegions.ini

Same issue. Thing is it works on another login on the same computer. Comparing both logs it looks like the base directory needs to be /Applications/Epic Games Launcher.app/Contents/UE4/EpicGamesLauncher/Binaries/Mac/

Both you and I have /Applications/Epic Games Launcher.app/Contents/UE4/Engine/Binaries/Mac/ as the base dir. I haven’t found a way to change it when starting the launcher.

PabloAtZozo · May 29, 2024, 6:53am

@sum_krispy_duck In my install path /Applications/Epic Games Launcher.app/Contents/UE4/EpicGamesLauncher/Binaries/Mac/ only holds temp.txt file.

I have tried executing using /Applications/Epic Games Launcher.app/Contents/MacOS/EpicGamesLauncher-Mac-Shipping directly and it worked! I don’t know the reason. I have not reinstalled or updated the app since my last post…

Could you try and confirm?

PabloAtZozo · May 29, 2024, 6:56am

Ok, so that worked. It notified me of an update and I approved. New version 16.6.0 installs and I get the same “invalid backend” error again

JamesMichael512 · May 29, 2024, 11:02am

Ensure ConsumingClientId=YOUR_CLIENT_ID is in PortalRegions.ini (located in the launcher’s installation directory). I replicate the same strategies on my clients’ websites, including https://wealthystars.net, and everything is running smoothly.

PabloAtZozo · May 31, 2024, 7:28am

I tried this but there is not PortalRegions.ini file:

DefaultPortalRegions.ini does not have an entry for ConsumingClientId.
DefaultEngine.ini does have those entries:

[EpicOnlineServices Prod]
ConsumingClientId=7a4...

[EpicOnlineServices Gamedev]
ConsumingClientId=308...

Where do I put it?

YusufRahman512 · June 22, 2024, 2:44pm

Try setting the ConsumingClientId in the PortalRegions.ini file under the EpicOnlineServices section, and verify your network connection or use a VPN to resolve potential regional issues.

PabloAtZozo · June 27, 2024, 4:34am

@YusufRahman512 Thanks but still does not work. I can’t use a VPN due to company policy.
