Authentication error when connecting to Salesforce Chatter

A flow that I had setup and working for many weeks suddently stopped working with the error happening in the step "post to group" in Salesforce Chatter.



The error seems to be in the connection:


Error Details
Error from token exchange: The connection (msmanaged-na/chatter/shared-chatter-0df33fac-e6a4-4b5e-8724-93a46c5d14c3) is not found. Please create new connection and change your application to use the new connection.


I have tried creating a new connection, and tried deleting all my existing connections and starting fresh.  Each time, after successfully authenticating to salesforce and granting OAuth permissions, Salesforce is returning this error message in the authentication flow:


 And the connection remains invalid.


Any suggestions?

Hi @Anonymous,


I afraid that connection you created is invalid.


Please take a try to create a new connection and make sure the connection that you created is availble.


Best regards,
