Athentication Error on all WIFI connections to any Fivem Server

What is the issue you’re having?

About 3 weeks ago this started. When I try to connect to any Fivem server wifi, I get the error “Failedto connect to authentication Services in a Reasonable Timespan.” I have tried on different wifi devices on different ISP’s. I can connect on my office LAN but not when I connect via cable to a wifi router. Like I said, this only began a few weeks ago as I have been playing on nnumerous servers for ages without any issue. I can ping Fivem )see screenshots) from my wifi connection.

What have you tried already to fix the issue?

I have tried different wifi services on different ISP’s, tried using my mobile hotspot as well. I have turned off my antivirus and firewall. I even went as far as to do a factory reseton my PC and reinstalled GTAV and Fivem. I have also tried using VPN’s.

What server did you get this issue on?

All servers including the Fivem test server.

Contact your ISP, chances are the necessary endpoints are getting blocked in wherever you’re located. Either that, or just play on a VPN.
EDIT: On a second glance, also verify Kaspersky isn’t messing anything up connection-wise, it very much can do so.

Thanks for the response. Thing is, my office LAN is via the same ISP that I use at home and I can connect to any Fivem server using that route. I have also tried disabling Kaspersky. I have tried basically everything that I can think of at this point. Really frustrated

Doesn’t mean that the routing is the same. You still need to contact your ISP and verify everything on their side.
