Getting an error Proxy server refusing connections

Issues

1. I am trying to access the web through proxy server and suddenly getting error "Proxy server refusing connections".
2. When I am going to Restart SafeSquid service from SafeSquid interface, it is displaying error "Proxy server refusing connections".

Root Causes

1. SafeSquid Process is not running.
2. SafeSquid is not listenning on the specific IP (or) port, where you configured in the client browsers.
3. Monit service is not running on SafeSquid Server.(When you restart SafeSquid from the Interface, monit service will start the SafeSquid service. If the Monit is not running, then safesquid is not going to start, till you  start monit service manually).

Troubleshooting

  1. Check status of monit service whether it is up or down.

Command :pidof monit

 If the ouput of the command is empty then run below command to start the service

Command :/etc/init.d/monit start

2.Check status of SafeSquid Service whether it is up or down.

Command :pidof safesquid

If the monit service is started already, then you will get the SafeSquid process Id

3.Check the listenning IP and port of SafeSquid by using below command

Command: netstat -tlnp | grep -iE "safesquid"

 

tcp6       0      0 :::8080                 :::*                    LISTEN      2741/safesquid tcp6       0      0 :::8081                 :::*                    LISTEN      2741/safesquid tcp6       0      0 :::8443                 :::*                    LISTEN      2741/safesquid

Check the IP configured  and  Port in your browser and compare with the above output
In the above command SafeSquid is listened on all Interfaces on the server with Port 8080,8081, and 8443
