Getting Error 505 - Anyone Know How to Fix This HTTP Version Not Supported Issue? or Error 505 - HTTP

Not a techie either, but error 505 drove me nuts till I found this:

In Firefox, type *about:config*, search for *network.http.spdy.enabled.http2* and set it to *true*.

If it still fails, the server’s just broken. Bookmark this site for later: https://httpstatus.io/—helps debug HTTP errors.
