EDIT #2: Looking into this issue further I have found that this feature, FEATURE ID: 26955 link is in the process of rolling out. I think this might have something to do with my issue. Any help would still be appreciated.
EDIT: I think something must have changed in how the connect to office365 button works or how grouping is done in teams. I found a strange workaround where if I create a group in Outlook and base my Microsoft teams group off that already created office 365 group, I can successfully connect to that group using my custom connector. But any time I create a team in MS teams, I don't see that team in outlook and then keep receiving the server error when trying to connect.
I created a custom connector last week for MS Teams and connected it to a few of my channels. This week I created a few new test groups and channels and the connector is no longer working. I keep receiving a 500 error from the connect url like the image below.
My old channels from last week still work fine with my sideloaded connector. Any new group and channel I create keeps running into the server error I see below.
Any help at all would be much appreciated. I have also managed to receive this error intermittently from connectors in the store.
Similar to this post from a few days ago, I am also receiving an error when I try to delete the sideloaded app: Custom Microsoft Teams Connector doesn't communicate with an external service at all
Error received from Microsoft connect url (Office 365 button)
