Web Connections Fail With "Unable to Connect to Web Proxy" Error

When attempting to connect to web targets through PrivX, the error "Unable to connect to Web Proxy" is shown. This usually indicates a problem with the PrivX Web Proxy service or its configuration.

Potential Solution

To resolve this issue, ensure the PrivX Web Proxy service is running and the configuration is valid.

1. Confirm the service is active:

   sudo systemctl status privx-web-proxy

   If it is not running, restart the service:

   sudo systemctl restart privx-web-proxy

2. Also on the Web Proxy host, ensure the setting privx_rdp_proxy_enabled = true is present in /opt/privx/etc/web-proxy-config.toml

3. On the PrivX servers, ensure the RDP proxy configuration file /opt/privx/etc/rdp-proxy.toml contains web_proxy_enabled = true

4. Using the PrivX GUI, navigate to Administration→Web Access Gateways to confirm network accessibility:

   • Verify the Web Proxy address is configured correctly -- prefer using an IP address instead of an FQDN, when possible
   • Ensure that the address is reachable by the Docker container running on the Carrier host (using default ports: 18080, 18443, and 18444)
