HA configuration ok, ping OK, but no sync

[sator]

Hello all,
I need help on a strange behavior of my firewalls 

I configured them with a subnet 172.16.31.0/30, the ping is ok, the failover is ok, but the XMLRPC Sync doesn't working

I can see the packets leave the master firewall, but can't see them entering the secondary (no deny neither accept)

I have the the rule to synchronize on port 443 (I also tried autorising all traffic, same thing)

I works few days, then nothing ....

Is the web UI listening on that interface and port? Best leave the UI to "All (recommended").
Is there an "allow all" rule on that interface on both nodes?

hello
yes, on both side it's listenning on the port 443

there is no event on the secondary on the firewall live view, look like I don't receive it, but the ping is working

the listening is 443
