New errors in email settings

1

After one of the latest bench updates, I’ve suddenly lost email connectivity. I went to the email account settings and was going to test another account but found I couldn’t save it. When I hit save, I get:

Server Error
AttributeError: ‘error_proto’ object has no attribute ‘message’

So, I just reloaded the page to abandon my changes and tried to save with the same values that were previously working and I get the same error.

If I go to Email Domain and open my domain, hit save with no changes… I get this:

Server Error
TypeError: Object of type ‘AttributeError’ is not JSON serializable

This was a previously working setup and as far as I know, nothing other than bench update has altered the system.

If I make a new account and accept all defaults, it will save. However, if I check Enable Incoming, then the attribute error appears.

Ok, we figured it out. Our domain transitioned to two-layer authentication which broke the email connection because it couldn’t authenticate. It’s too bad the error messages didn’t have more meaningful clues!

Have you server side access to the logs to post the complete traceback?

The only log info I could find that seemed to be related was in node-socketio.log:

{ Error: unable to verify the first certificate
at TLSSocket. (_tls_wrap.js:1116:38)
at emitNone (events.js:106:13)
at TLSSocket.emit (events.js:208:7)
at TLSSocket._finishInit (_tls_wrap.js:643:8)
at TLSWrap.ssl.onhandshakedone (_tls_wrap.js:473:38) code: ‘UNABLE_TO_VERIFY_LEAF_SIGNATURE’, response: undefined }

Anyway, I have it working again but I’ll need to figure out if two-factor authentication is going to be feasible.

Update - not sure how I missed it but here’s the complete traceback:
