I am getting the following error in Post message in a chat or channel step: A client certificate or authorization header was not provided. I have refreshed the Teams connector, I have removed the Post message in a chat or channel step and readded, and still receive the error. Any advice please?

I have this same issue intermittently across multiple flows, sometimes it is 1 run in 20, some times another flow will work 15/20 times in a row then fail three times in a row then work again, I have tried creating new connectors, setting a duplicate action to operate after a delay on failure, nothing seems to resolve this permanently, and I currently have three flows that used to work consistently; but now regularly have this issue!

I have errors when sending automatic approvals, after they generate error resends the flows and only until that moment they remain in execution waiting for a response.
