Server only accepting connections from game lobby

[Ragnoji]

I had message "Server only accepting connections from game lobby" when trying to connect to my server. I have no problem connecting from sandboxed csgo processes, so the problem is not about my server cfg. I used main branch tiny-client. Any tips on solving this problem?

This is weird, definitely there is something different on your server. Normally each server will get a reservation id from GC after sending hello. But on your server the cached id is 0. Did you see if the requested reservation id from the GC in the client console output is valid? Can you paste the console output here after removing sensitive information?

Is it stuck here? It has a 60 seconds time out if you wait a little longer. Looks like your server had never sent hello to GC. Are you using some plugins or extensions to bypass this? Maybe to fix the #Valve_Reject_Connect_From_Lobby?

i don't think i use any plugins, this is my folders in csgo

i also waited those 60 seconds before, there was no improvement

Then most likely that something is wrong with your steamclient api, I guess. Are you using all the pure server files or some of which are modified? Like no steam server or any other modification related.

Bump => Issue still present with non modified Servers. Reservation Cookie is 0 (when not spoofing the Reservation ID Serversided)
