JAllemandou moved this task from Next Up to Done on the Data-Engineering (Q4 FS25/26 April 1st - June 30st) board.

Having discussed this with Traffic, this was related to SSL handshake problem (regular traffic), that was incorrectly logged by HAProxy in v3.0. The logging is now fixed with v3.2. Calling this done.
