Hello Community ! I've read the forums and came across a few post where users are having difficulty "checking" to see if the ports are open. "Error 110" you might know it as. I came across the same issue myself after opening the selected port. Before making a topic requesting for help/ticket. Make sure you tried to run the "program" and make it listen to your selected ports. Afterward run the "check" again and you should get a successful completion! Made this topic as couldn't really find a clear straight forward instruction on the setup. If anyone else has something to share, feel free! Thanks for reading!
