This error message indicates that the system encountered an unsupported scheme while trying to parse a proxy URL. Specifically, the ‘socks5’ scheme is not supported.
A proxy server is an intermediary server that acts as a gateway between a client and the internet. It provides several benefits such as increased security, anonymity, and access to restricted content. However, not all proxy servers support the same protocols or schemes for connecting to them.
To resolve this error, consider changing the scheme of the proxy URL to a supported one such as HTTP or HTTPS. You can also try using a different proxy server that supports the ‘socks5’ scheme, or consult the documentation of the proxy server to check if it supports other schemes.
