[BUG] Only 4 fights in Guild Wars and connection problems

Hi. I play on PC. I did only 4 fights in Guild Wars today, and I won each of them, but I can’t make the 5th fight. Seemingly, I would have make 5 fights, and lose one of them. But my profile page shows I have no defeat this week.

I don’t know if it is related, but since a few weeks, I am very often kind of disconnected in the game. When I open guild tab, chatbox or whatever, or when I end a fight, I have a message saying a mistake happened with the connection to the server or something like that. And on the steam forums, I saw other players have the same problem.

Is my problem about guild wars could be solved ? Should I expect to be able to do the fight I couldn’t make ?
