I installed CentOS 6.8 and the cwp.client cpanel alternative thingy.
I have Let’s Encrypt up and running (after only about 100 tries) and it (mostly) works.
I have 3 domains on this virtual server. The first two (vbcalaska.org and camliwa.org) both installed their LE certs just fine and I’m getting a secure connection. The third one (victorymin.org) gives me this error…
Read your web server logs, check the configuration, see what’s wrong with that URL, make sure the Let’s Encrypt client is putting the challenges in the correct place.
At the moment, “http://victorymin.org/.well-known/acme-challenge/H7OyBx3ov6mmIth2X7RSSP8Ok8Mg53_uRVVg_sEkvcE” redirects to “http://www.victorymin.org”. Redirects are acceptable, but that destination is most definitely not an ACME challenge file. In fact, that URL may be considered invalid because it doesn’t end in a “/”. (I don’t know if Let’s Encrypt cares.)
I can’t be certain that’s what your web server returned when Let’s Encrypt checked – in particular, it may only return the problematic redirect for files that don’t exist, and it may have existed before – but it might be a place to start.
If the redirect is the issue, you’ll have to adjust your web server configuration so… well, so that the redirect isn’t an issue. Either carve out an exception so that URLs starting with http://victorymin.org/.well-known/acme-challenge/ do not redirect, or make ithem redirect to URLs serving the proper challenge files (maybe http://www.victorymin.org/.well-known/acme-challenge/).
In fact, that URL may be considered invalid because it doesn’t end in a “
