What did you do to get this issue? Upon joining the server my little brother receives these errors on console for each mod, and this connection failed when all mods are “downloaded.” I join perfectly fine. Sadly I live away from him so I can’t determine if it is a network issue.
What server did you get this issue on? Kraken Gaming v1.0 | Real life Roleplay
CitizenFX.log file I can’t get it.
.dmp files/report IDs No access

If an issue with starting:

Filepath to FiveM folder

Did you try to disable/uninstall your Anti-virus?

Also add what you already tried so far. I have gone through many forums about this same issue and tried the fixes. I have turned off firewall. Reinstalled GTA and FiveM. Installed and reinstalled Rockstar launcher and social club. Cleared cache too many times. restarted the computer. checked game integrity. checked ipv6. tried to run as administrator to find fivem doesnt allow for it. checked gta pathing. and made sure canary isnt running.

Please also describe the issue you are having, providing as much information as possible will help us to help you. A good format you could use: what have you tried to do, what did you expect to happen and what actually happened. The above is the best I can describe the issue.
