Hi,
Thank you for your quick reply. Unfortunately I had no chances to change my network connection in any way. But we just restarted the IceScrum process on our server and it worked. So for the moment we are okay 🙂
Anyways, I can’t explain actually what went wrong but restarting IceScrum itself did work. So it doesn’t seem to be a local problem of my PC?!
I will reach out to you if this issue comes back again.
Thank you and best regards
