Cannot Open Let'sEncrypt on cPanel

The error you are getting is reaching port 5959 on your own server. Is there a firewall or anything blocking it ? That port seems an odd port for cpanel as well. I think you’ll need to contact the developer of taht script at


Problem Solved: I edited the license myself for the new domain name, but you actually resubmit for a new license for hostname changes. If you have changed host names, go to

Thanks for the advice!
