Could my local network configuration or ISP be contributing to an ExitLag 502 error, even if it's generally server-side?

While a 502 error is primarily server-side, your local network configuration or ISP can indirectly contribute to it. A highly restrictive firewall, an aggressive antivirus, or specific router settings (like certain NAT types or port blocking) could interfere with ExitLag's ability to establish a proper connection to its proxy servers, which then receive the bad gateway response. An unstable or throttled ISP connection can also make it harder for ExitLag to maintain a consistent link, potentially leading to errors.
