Any recent changes in ACE? Getting "could not get public key with keyId" error

Running a really simple ACE app, and getting an “Authentication verification error (404) : Could not get public key with keyId ” error.
I updated the underlying ACE app by deploying a fresh app and copying over my app’s files.
Not seeing any major difference between my config.json and the base package’s.

Anyone encountered this? Any ideas?

Hi Bob, super weird that this is happening to you. Could you please email me at so we can get to the bottom of this issue? thanks

We narrowed it down to a firewall issue in the end. Worked fine outside the FW.

Realized the addition of forms opened a previously unavailable option for achieving our goals and realigned things to be native to Jira and removed the need for the connect app.

Thank you for the reply!
