2026.9
Changes
Fix egress-proxy mistakenly returns 421
In previous release 2026.6, if an origin certificate was generated with uppercase characters, the egress proxy could fail to match the request hostname. This resulted in either a 421 Misdirected Request response or an unrecognized_name (112) TLS alert. The issue was caused by a case-sensitive hostname comparison when validating configured hosts. Since DNS hostnames are case-insensitive, this behavior was incorrect.
This release fixes the issue by performing hostname comparisons in a case-insensitive manner, ensuring correct request routing regardless of character casing in the origin certificate.
