v.23.7Improvement

Session creation robust to unreachable IP addresses in HTTP endpoints

Official CH changelog text
In cases where the HTTP endpoint has multiple IP addresses and the first of them is unreachable, a timeout exception was thrown. Made session creation with handling all resolved endpoints. #52116 (Aleksei Filatov).
Improved HTTP endpoint connection handling by attempting all resolved IP addresses instead of failing on the first unreachable one.

Why it matters

This feature resolves the issue where a timeout exception was thrown if the first IP address of a multi-IP HTTP endpoint was unreachable. It enhances connection reliability by trying all available IP addresses when creating a session, reducing failures due to unreachable endpoints.

How to use it

No specific user action is required. The session creation process now internally handles all resolved IP addresses automatically.
