I've just tested and deployed an application to RHEL 7.3 with PAServer.
One of the things I've discovered is that the firewall is by default enabled on RHEL 7.3, so, after copying PAServer to RHEL and running it, you won't be able to connect. You'll need to run the following commands first:
The above commands open up port 64211, which is the default port that PAServer listens on, so that RAD Studio can connect to it.
Once you've done that, RAD Studio should be able to connect successfully.
