See my other thread https://forums.unraid.net/topic/190733-712-outgoing-proxy-how/
Unraid uses the "strange" testurl "https://www.msftncsi.com:80" which is denied by standard configured proxy servers.
Requesting HTTPS on a normal HTTP port is usually forbidden in proxys like SQUID. Therfore the test fails, UNRAID retries endlessly unless you delete the configuration again.
Change the test to "http://www.msftncsi.com" , this is what Windows Boxes use and what succeeds.
