Port 2030 does not open

I installed it on an EC2 server from amazom (Redhat 7).

When you access the IP on port 80, the message (It works!) Appears,

But when I go to the panel on port 2030, I can not access. Message:

NO PE POSSIBLE TO ACCESS THIS SITE
ERR_CONNECTION_REFUSED


The door is open in the AWS Security Group.

Try

service iptables stop
service httpd restart
service named restart
service cwpsrv restart

I did what he said, but it still did not work.

See:

can you try

yum reinstall cwpsrv

Although this might not help the poster in this case,
I had a similar issue with an AWS Lightsail instance and just wanted to share my solution.

The problem for me was that the Lightsail instance did not have port 2030 open.

By default, the AWS Lightsail instances only have port 22 and 80 open. So you have to go to your instance in the lightsail control panel and click the networking tab and add port 2030 (I added it as 'Custom' over TCP).


(While you're at it, if you plan on using SSL(https) on your website/app then you need to open port 443 as well.)

Just thought I'd share!

Sometimes when you're doing something new (in my case CWP) it's easy to overlook even the most basic of settings because you mistakenly think there's something wrong with the new stuff! :>

And best practice is to run everything under HTTPS -- so you can skip 2030 and go for 2031 instead. I prefer that, as well as 2096 for webmail, instead of HTTP on 2095. (I prefer not to follow cPanel's port conventions, though -- I don't like using 2087 for the admin panel.)
