Haproxy service won't start when keepalived service is running

Hi All,
I am trying to configure haproxy with keepalived but if I start keepalived service first, haproxy fails to start. When keepalived service is stopped, haproxy starts without any problems. I get the error below when I attempt to start haproxy manually while keepalived is running:
Proxy ‘webserver’: unable to find local peer ‘VIP01.domain.com’ in peers section ‘mypeer’.
Fatal errors found in configuration.
Control process exited, code=exited status=1
Failed with result ‘exit-code’.
Failed to start HAProxy Load Balancer.

The system is Centos 8 and I found the article below and checked if net.ipv4.ip_nonlocal_bind sysctl is set to 1 but it still doesn’t start when keepalived is running.

I would greatly appreciate any help.

can’t really help since i’m just learning and i’m far from an expert.
i just wanted to ask you maybe you found a solution and you can update? there’s a lot i need to learn and i hope this might help me. thanks

Maybe you can show config of both services, so we can realize what is the problem.
Best regards
