Hello Paride, today i recreate my bigger configuration with Debian 10 and 11

LB Manager over proxy is fully workable. - - - - - - - - - - - - - - - - - - - - - - - - - LB Manager Upgrade -> Debian 11 with Apache 2.4.48-3.1+deb11u1 If i go to the LB Manager directly one log entry after first connect :~# tail -f /var/log/apache2/management_error.log [Thu Aug 19 12:51:20.867073 2021] [proxy_balancer:error] [pid 459:tid 139790420895488] [client 192.168.56.1:13139] AH10187: ignoring params in balancer-manager cross-site access and LB Manager is operational.
