Unfortunately we run into issues with Synapse and have to maintain our services. This is why our chat system is down. That can happen more often the next days.
So we decided to postpone the update for the TS5 Client beta 74
.
It will be released today in the afternoon (it’s ~12:30 PM here).
The main change in there will be that client will be able to connect to server even when the messenger or myTS service are down.
