Error testing custom connector in GCC

I'm getting the following token error when trying to test a new custom connector.


Is this an issue or limitation with the current state of the Government Community Cloud (GCC) instances of PowerApps?



During the setup of a new connector, when clicking "Test operation" on step 4. Test.


Error Message:   Operation failed (400), see response below

Hi @ecornell ,


You should use a different set of URLs to access PowerApps US Government

More information:



And more information about GCC



Hope this could be helpful.


Best Regards.


We are using the new government URLs to create and test the connector.

Is this issue resolved? We're still getting this on our environment. Thanks.

No, custom connectors are still broken in our GCC environment.

Hi, I'm working for another organization using GCC and we are running into this same error message while doing the same thing. We've validated in a regular commercial tenant that everything works as expected but the same settings in a GCC tenant are resulting in this error.

We thought it could have something to do with the fact that my organization is using a Commercial Azure tenant while the Office 365 tenant is GCC. Are you setup the same way or is everything GCC? If not, then it could just be an issue with GCC in general and Microsoft needs to look further into this...

Getting the same error, not sure if you have found a fix to it.

I had a ticket open with Microsoft for a few months and they finally told me they believe the test functionality is broken in the configuration window of custom connectors in GCC tenants. Sure enough, when I added the connector to my Flow and ran it there it worked as expected. May want to just ignore the test tab for now and see if it works.
