No connection possible to

After setup of an test flow using i wanted to port it to our production and moved the sources to

but i can't connect to luis with the flow connection. Error 401. Only the connection to us is working.


In my computer vision i have to give the related endpoint i connect to so i suggest it is an bug and the connection

is routed per default to us region where my eu.luis is not stored. 


The test via luis.console is working for my given key.

Hi @  DanielNuremberg,


Could you please share a screenshot of the configuration of your flow?


In many cases, flows fail because of an authentication error. If you have this type of error, the error message contains Unauthorized or an error code of 401 appears. You can usually fix an authentication error by updating the connection.

You could refer to link below to troubleshoot the flow:


Please check if the flow fails because of an authentication error,please let me know if your issue could be solved.

Hi @v-yuazh-msft,


find attached the error: 


"Could not retrieve values. (401) Access denied due to invalid subscription key. Make sure to provide a valid key for an active subscription."




I checked every possible key and it is not working. (Azure Key1+2), Authoring Key, LUIS Starter Key.

When i test my given Key with the LUIS console all is working fine and i get an response, but not in the flow.
