Issue in MS Teams chat UI action

[nameisnani]

hi team 

we are getting issue like this [ ' Invalid access token. Please check  your credential alias ' ] and 

HTTP Error 401 - Unauthorized

when we are clicking on  ms teams chat  UI action button in Incident form, as shown in below 

from the logs we found this message 

can anyone please provide where should i update and what needs to be updated.

I have followed this step also 

- Please delete oAuth token by navigating to "System OAuth > Manage Tokens" and locate the token for the user who receive the error message which prompts for login when he tried to open teams chat again.

after that also not working .

Please hlep me

it clearly says invalid username or password or issue in getting the token

was this working fine earlier?

are you sure you configured the OAuth app registry correctly?

If my response helped please mark it correct and close the thread so that it benefits future readers.
