Broken Custom Connector connection


I hope to post the question on the right forum.

I had a pretty weird scenario today. I have a Custom Connector that has been working fine for a few weeks, and it suddenly broke today with the error "AADSTS7000215: Invalid client secret is provided".

My first thought was to check if my secret key has expired on my AAD. I was surprised that the key did not expire at all. I updated my Custom Connector with the same configuration, and I was able to authenticate my custom connector without any problem.

Can anyone guide me to the real cause of the problem and why a simple update of the custom connector solved the problem?

Hey @melamri ,


You might want to use the Flow Studio(AKA Power Studio) -> In Flow studio if you click on the broken connection and select connection JSON and might get the excat reason for the Error.


I had used this tool a long time back and got to know that for my broken connection the reason was -> Failed to refresh access token for service.


Or you can create a support ticket and they will help you investigate the problem.
