Bracket TLS connections intermittently failed

Incident Report for Mailprotector

Resolved

Earlier this morning, Bracket encryption scaling added resources that did not respond to connection requests correctly. Users may have received a bounce notification if their encrypted email attempt connected to this subset of resources. The bounce notification error was:
The bounce is: : host encrypt.bracket.email[18.223.92.55] said: 550 A secure TLS connection is required.

The problematic resources were identified and removed, and the issue has been resolved. Users can send encrypted Bracket emails as expected.
