Error "The proxy server is refusing connections" during Web Connections

Symptoms

Browser displays "The proxy server is refusing connections" or similar error message when connecting to web targets.

Verify your Proxy address setting at Administration→Deployment→Deploy PrivX Web Access Gateways. It should contain the IP address or DNS name of your PrivX-Web-Proxy machine. Make sure your web proxy ports are accessible from Carrier host.
If the problem persists, verify and restart the Squid service on your Web-Proxy machine:

Make sure your Carrier-host web address is allowed by some acl localnet src directive in /etc/squid/squid.conf
Also, if your web site uses custom HTTPS port, add it to acl SSL_ports.

Verify and restart the Squid service with:
```
# systemctl status squid
# systemctl restart squid
```
You may also check Squid logs under /var/log/squid/ for additional information about the issue.
