If your end goal is to use the self-signed cert, no other action is required once you specify a port for HTTP. That's because Xeams will automatically download a file from Synametrics web site that can be used out-of-box. 

If you're running into problems, check Xeams.log for errors and either post them here or send us an email to our support department. A restart in Xeams is indicated by a bunch of dashes in the log file. Refer to errors after you restart.
