Quite odd...
Everything has been working for sometime now.
Now, in the last week I have been getting SSL Handshake failures and unable to connect to the server. I tested the the syntax and noticed it started to complain about the cipher suite, so I remove them but with no luck.
it loosk like it'a VIP issue. I am now unable to ping the address from the same subnet. I can ping the gateway but not the vip.
I have updated the OPNSense to OPNsense 21.1.9_1-amd64
and have rebooted the box with no change. I can ping the VIP from the OPNSense itself.
