Description

Reopening https://redmine.pfsense.org/issues/16596 since the author mentioned it shows as a warning
1) Because the closing comment says incorrect information as this is not the case (pfsense 2.8.1) - restarting service nor stopping it and starting made a difference, also the message does not say I should do anything beyond applying changes

2) Even if it was the case, if restarting service did not do anything, would I need to restart the entire pfsense? That makes no sense! I have tried stopping the service and starting it for the Service status menu and that did not make any difference. I spent 2 hours on new years eve with this so thank you very much.

This is a pretty nasty bug which is in pfsense for years (see https://forum.netgate.com/topic/184401/haproxy-seems-to-forward-to-wrong-backend-port?_=1767279314113 ) - the solution with `load-server-state-from-file none` and stopping and starting the service was the only solution that worked for me. The way I figured it out was thanks to haproxy stats - hovering over the backend name showed the IP and old port.
