Hello There,
In case you still need assistance with this issue, kindly check below
- You have tried to perform site pairing with both FQDN & IP of remote HCX and still it doesn't work means it is not DNS issue
- From your point about "I made a test-netconnection -port 443 on that ip from another machine in that network segment with windows", I couldn't understand if the test was successful as in TCP port 443 from local to remote hcx is open or not? Also, kindly take source machine as your local HCX machine from where you are trying to initiate the site pairing.
- Is this local HCX supposed to use a Proxy Server. In that case, even if you opened port 443 on the firewall for a Direct Connection, but HCX will ignore that and will try to send the traffic to the Proxy instead.
- Based on the above suggestions, after any change performed on HCX, kindly restart app and web service via hcx:9443 URL
