@Barnabas @markk hi guys I spent a lot of time finding the source of that issue and today I think I could find something. So this problem is only on the Telekom network, mobile and wifi too. I talked to the Hungarian Telekom support a few hours ago and they confirmed to me that the endpoint is disabled on the network and said that the problem will solve official during the next 72 hours but till morning can be solved too.
