Hi @Stephen Weber,
You can use the netstat command to verify port 7248 on the server to see if there is another application running on the same IP/port combination.
Use the command netstat -abn > netstat.txt
to output the contents to a txt file, then search to find 7248 and see what executable is listening on the port that way. I suggest you try using a different port for binding and assigning the ssl certificate.
