When using OGS on my mobile phone, I frequently see the rose block “Fehler beim Verbindungsaufbau mit dem Server! You won’t be able to play any game or receive any notifications until the connection can be reestablished!”
This happens when being on wifi and also on GSM.
The block disappears after a while. Everything done before the block appears is lost. After the block disappeared everything is normal.
I seems to me that the timeout for the background ajax calls is too short for mobile communication. Could that be?
