Hi, today we installed Expressway E and C. Traversal Zone worked well. But when we want to login via MRA we see in the Log that he can not access URL of Expressway E via Port 8443. Also with a browser we dont get an answer. Port 443 work well.
We also tried to access the Website from a host in the same subnet. This also dont worked, so its not an firewall issue.
What kind of an answer do you expect to get when trying to access Expressway-E with 8443? You won't get the web admin panel. But did you also check in the Firewall that the traffic is reaching you and it is not blocked?
Anyway, you must configure the '_collab-edge._tls.domain.com' SRV record in the public Internet DNS with port 8443. Otherwise the MRA won't work, and when a softphone is trying to resolve the SRV record of your domain, it won't know that it should reach port 8443.
