Good hint. Will take care about it.
I just tryed to get free SSL certificate here:
https://www.sslforfree.com/And I did verify my domain name, using "Manual Verification".
Then I did upload that file, in "/.well-known/acme-challenge/" folder.
To create "/.well-known/"-folder on windows, I did use the command:
cmd.exe
cd folderpath
md .well-known
Then, this service return me SSL certificates.
But... Is see this was been registered to
www.blahblahblahblahblahblahblah.611.to, not for
blahblahblah.611.toSo this seems, like invalid certificate.
P.S.:
ZeroSSL also provide the SSL certificates for
www.domain.name, not for
domain.nameLetsencrypt should work fine.
Take care to register the d/DOMAIN object for both itself and WWW, like i.e.:
{"ip":"1.2.3.4","map":{"www":{"ip":"1.2.3.4"}}}
