Identified

We have identified an issue with the SSL chain that our Redirector service uses for the most recent Let's Encrypt SSL certificates. This issue only impacts domains with URL redirects with HTTPS sources and SSL certificates issued from August 20th onwards. This issue doesn't impact URL redirects with HTTP sources.

Our team is actively engaged and will release a fixed certificate chain momentarily.
