Hi, my company has a GlobalProtect VPN and I've been successfully using it using GPopen and openconnect for years. A few months ago, they changed something in our network or VPN that is causing the VPN to fail to connect via ESP when I'm in our office, though it works perfectly fine outside the office network. I have tried to figure out what exactly is preventing ESP from starting up and the only thing I can really see in the logs that is different between in the office versus out of the office is this log
Jul 30 11:06:33 xps15 plasmashell[3116179]: 2024-07-30 11:06:33.467 INFO [3116179] [GPClient::onVPNLogAvailable@518] ESP receive error: Connection refused My question is, what does this log line imply and where is the connection being refused from? Is it just UDP packets to the gateway address? Prior to this, it does do a handshake using Okta to sign in which works just fine so it's transferring the ESP packets explicitly that seems to be the problem. To me, this suggests a network configuration/firewall issue but I need more info to tell our networking team what to investigate. Any help would be appreciated. Thanks!
