#3 Titan Quest Anniversary Edition Server Issues

“My friend and I tried to host a Multiplayer Internet game. We connected to each other games but the ping is atrociously high: 600-1200ms despite the fact that we are in the same area. Why can’t we directly connect to each others ? Or the information is being sent to Nordic server then sending forward to another player ?”

A lot of players are complaining about the Server Browser issue, they say that it’s glitchy and broken. For example, this is what a user said on the Steam Dashboard: “Anytime I try to look through the servers, it scrolls me back to the top of the list. If I click on another server, it puts me back at the top of the list, making it impossible to find a game, let alone join it. If i want to join a game I have to click on an available server on at the top of the list of servers and then click join as fast as I can before it puts me back at the top of the list. I love this game and want to play it with others but as of now I cannot. Please fix this soon, I love this game.”

Solution: A player came up with a fix for the server issues, check it below:

First, I got the list up.
Disconnected from wifi.
Selected friends game.
When the password screen came up, I reconnected and waiting a moment.
Put in password, joined game (also alt-tabbed to make sure my firewall wasnt clogging).
Am now in game.
