WIO, example with HTTP or HTTPS ping?

Documentation for WIO has several examples but all of them use PING. Some hosts ignore ping requests and HTTP or HTTPS has to be used in such cases.

Unfortunately, some hosts are reported as INACTIVE even those are OK. I cannot explain that, why sometimes test works and sometimes it doesn’t work. I should list here some examples but I am not sure if that is a good idea to highlight troublemakers in public…

The question is, what to enter to FQDN field for HTTP or HTTPS test. Just a hostname? Or Full URL? Maybe I want to test a static page on HTTP server, in that case I have to enter URL of that page. I would like to see example in documentation…
