Chatter connector error 400 when trying to connect - PowerApp failure connecting to Chatter Login

Was using the Chatter connector for months before it suddenly stopped working.

Checking Flows and saw that the Chatter connection was failing

Attempted to fix connection but once the PowerApp popup window opens it give error 400 URL not found.

Hi @DShaw,


I am afraid that there might be some updates on this connector. When testing with it, it returns the same error message on my side.


Please try again with it later, if you are still having the issue, please post back.



Best regards,

HI Mabel @v-yamao-msft


Than you for your reply.  Gave it 3 days and the Chatter connector is still erroring.  Looks like the PowerApp for the connector needs updated with new Salesforce Chatter login URLs.  Any ETA on getting this fixed.  Certainly not making me feel warm and fuzzy about investing in the Premium version of Flows when my trial expires.



FYI  The Microsoft Teams flow also has issues/bugs  when you include dynamic fields it posts the expression.  For example it posts "@{triggerBody()?['Title']}  instead of printing the contents of the title field from the trigger (which is SharePoint new item created).  I will enter a new post on this issue.
