Which protocols are supported by Limeproxies? Vinora June 11, 2018 07:03 LimeProxies supports HTTP and HTTPS protocol (Port no. 1212), and SOCKS (Random port assigned) Related articles I received my proxies but I am unable to use them. What do I do? How do I handle a 407 error message (Proxy authentication required)? Can I use Limeproxies on more than one device? Do you provide userbased authentication for Socks Proxies?
