Admin URL ERR_CONNECTION_RESET

I've had the server running fine for a few months, as of this morning the admin URL (both ports 2030 and 2031) are giving the following error.


This site can’t be reached

The connection was reset.
Try:
Checking the connection
Checking the proxy and the firewall
ERR_CONNECTION_RESET


I'm not seeing any server updates done via any crons or logs and I'm not certain what the cause is.  Websites are still running, I've tried disabling and rebooting various services (iptables, apache, nginx, varnish).  Any guidance would be appreciated.

you should check if your cwp is up and running, you can do that by using command

Code: [Select]

netstat -tulpn|grep 2030

You can also check the state of your service by running this commands

Code: [Select]

service cwpsrv status
service cwp-phpfpm status

It's all good.

Code: [Select]

netstat -tulpn|grep 2030

then check your CSF firewall, you can disable it for first test and if this is firewall related don't forget to add cwp ports on the TCP_IN and TCP_OUT list in csf configuration file /etc/csf/csf.conf

After making changes restart firewall

Code: [Select]

csf -r

CSF looks good.  I also disabled it and restarted it, but still could not pull up the admin via either port at any part in testing CSF.  Even attempted disabling iptables while testing CSF.

then you need to check port limits with your server provider
