Hi Daniel,
thanks for the quick reply, unfortunately it's not the meta rights.
On a client also comes a 401 at the browser login but then it tries to call localhost:port.
On the server itself it remains with the 401.
The user is system administrator in the global webcon rights.
Best regards,
Matthias
Hi Matthias,
I have no idea, why the client would retry with localhost upon receiving a 401.
On the server you may receive the 401 due to LoopbackCheck. There are two options for this, so that you can connect to the portal on the server.
