Hello @Codeman, welcome to the forums!
Do you have any firewall or other software that might interfere with the game?
What’s your current internet speed and ping to the server?
Are you connected to the internet through a wired connection or via wireless?
We’d suggest also trying to run the game with any firewall/AV software fully disabled, even if you have had it configured for the game’s client, just to ensure that it’s not interfering at all.
If the issue persists, could you check if you have UPnP enabled in your router and that all the necessary ports are open?
Lastly, please share your latest log of an unsuccessful server join attempt, which can be found in ConanSandbox/Saved/Logs, as well as your region and ISP.
