HA on KVM not working over the LAN

Hello everyone, I’m pretty new here. I installed HA on KVM and everything worked fine, I can see HA.
But I can’t open the URL of the HA from Windows or from the HA application, what am I doing wrong?
I read that people create a bridge and I also tried that and it didn’t help me.
Would appreciate help.
I looked at this example

Thank you!
