Hello.
This was further investigated by our programmers. From what we can see, the issue is very likely not backend related. If this were an issue on the backend side it would return a different error. 0x00010001 (“server is unreachable”) error is related purely to the client connecting to the server and that connection works entirely without the backend. The only thing we can suggest at the moment is to have an IT specialist to help you troubleshoot and fix the connection issue.
