Unable to see or join any servers unless connecting through a mobile hotspot

Game mode: Any
Type of issue: Misc - Unable to connect
Server type: Any
Region: United States

For about a month now I haven’t been able to see any servers in the server browser or connect to them. Using Steam’s server browser I can see the servers, but attempting to connect brings back a “Failed to Join Requested Server” error. I’ve tried everything I can find and the only way I can get the server list to populate and be able to connect is by using a different service altogether, in this case a mobile hotspot. My internet connection is completely fine and I can play MMOs and Civ with my friends no problem.

Things I’ve tried (that I can remember):
*Letting Conan Exiles through firewall
*Disabling firewall and antivirus
*Verifying files
*Uninstalling and reinstalling the game
*Uninstalling and reinstalling Battleye as admin
*Using Steam’s server browser (as mentioned above). Also tried this on both official and unofficial servers and it brings back the same error.
*Forwarding ports
*Setting max pings/minute to 500 in Steam settings.
*Disabling Steam overlay
*Uninstalling Nvidia Experience
*Flushing DNS cache
*Resetting modem and PC
*Updating Nvidia driver
*Having Nvidia Experience optimize the game
*Creating new hosts file

Server filter is set to Internet and no mods are installed. ISP is Comcast.

Any help would be appreciated, I’m not really sure what else I can do.

Hey @Father

Welcome to our community.
What ISP are you using at home?

[Father]

I use Comcast/Xfinity at home.

Could you try a possible workaround just to confirm suspicions? If you use a VPN, can you see and/or join a server?

[Father]

Just tried a free VPN with a data limit. The server list populates as normal and I am able to join servers no problem with it running. Unfortunately I don’t normally subscribe to any VPN services, though it is a better alternative than using my phone as a hotspot. Does this confirm the issue being my ISP?

[Ignasi]

It would seem like it, for some reason it is not allowing contacting the master server to fetch the list.

[Father]

Well that’s unfortunate I’ll use the VPN for now and hope they can resolve it. Thank you very much for your help!
