When you click the “join” or “invite” buttons in the Party interface without typing a player’s name, this error appears:
The game client is unable to gain access to the log-in server at this time. This is most commonly caused by a firewall or router settings, security applications, or connecting through a campus network. For additional support, please visit http://support.guildwars2.com. (Error code 10:1001:8008:712:101)
At first, this was very confusing to me, because I didn’t know what I was doing wrong, and I thought that my game was glitching. It would be much more informative to have a friendly message along the lines of:
Please type a player name to join their party!
