Using a VPN may or may not bypass HTTP Error 407, depending on the specific circumstances of the error. If the error is related to a specific proxy server, a VPN may help you bypass the proxy and connect to the website directly.
However, if the error is related to the network or internet service provider, a VPN may not help. In some cases, a VPN may even cause additional connectivity issues, so it’s important to proceed with caution and troubleshoot the underlying issue before trying a VPN as a solution.
