Hello,
not sure if this is also related to the mentioned problem or if you were aware of this happening, but there was a crash earlier today, January 23rd around 1 AM French time.
A similar thing also happened yesterday, around the same time as well, though the two crashes seemed different.
However, both times the Playroom recovered by itself.
in yesterday's crash, the website continued working, it would appear that the web client connects to the game server too since it said connection established, but didn't receive any data and the game toolbar was empty. On the other hand, the Windows client would get stuck on done reading headers, and it would continue playing the connection sound until you force close it, not even opening the service status page this time. After about 10 15 minutes, everything went back to normal.
Today, around 1 AM, the Playroom crashed. I was online at the time. I was playing Uno with super interceptions and a time limit of 4 seconds, and for a while it seemed like the old Uno crash returned. My Internet was really bad for a moment, and after my opponent played a wild and chose a color, it was my turn apparently but I couldn't do anything, and the time limit stopped going as well. For a while, I was able to receive data from the server and I could hear people enter and leave, but I couldn't really send any data, i.e shortcuts did not respond and I couldn't send chats either.
I tried opening the site while this was going on, and I received a message that Playroom is unavailable because of a maintenance operation. After about 10 minutes, this returned back to normal as well, though as soon as it did I could hear more than 20 messages of people from my friends list leaving and entering as well as other people reconnecting.
After this was over though, the Playroom continued working normally.
Hopefully these problems can be resolved.
Edit: The exact same crash happened tonight, and at the same time too, around 1:15 AM.
This time I wasn't in any game, but it was the same as described above, I was unable to send any data to the server for a while, occasionally it started working again and then stopped, the website said it was under a maintenance operation, and after about 10 minutes everything returned to normal again with that one exception of people being reported to constantly leave and enter the Playroom for about 30 seconds.
Edit 2: Definitely seems to be a daily occurance now, crash today at 1:10 AM as well for about 10 minutes. January 25th.
