Yesterday/today some of my flows started failing with the following error:

Error from token exchange: Bad Key authorization token. Token must be a valid JWT signed with HS256
Failed to validate token: <token>: Signature validation failed. The token's kid is: '<kid>', but did not match any keys in TokenValidationParameters or Configuration.

Searching online, I was able to find many references to:

Error from token exchange: Bad Key authorization token. Token must be a valid JWT signed with HS256 Failed to validate token: <token>: X509SecurityKey validation failed. The associated certificate has expired.

which seems to clearly suggest expired authentication. It is, however, still seemingly different from my error.

Anyways, I was able to fix my error by re-saving my flow, as many people suggested for dealing with the other error. However, I was wondering if anyone can confirm an actual root cause and permanent solution for my error. It's simply not acceptable for my flows to start failing after some period of time and then require manual intervention to be able to be resumed.
