To my understanding there was an IP address change for this server on the 27th of October. Since then the server has been appearing on the server browser but has been unreachable, holding a player count of 0 for the past 2 days. When trying to access the server I (and my friends) get the error message:
CONNECTING FAILED (0x00010001)
"Could not connect to the server because it is unreachable"
Most other servers are working fine but me and the boys have put in quite a lot of time building on this one so hopefully this can be resolved 🙂
