I have strange situation and I don’t know how to solve this problem.
When I installed SSL Letsencyprt everything looks fine till I testing on SSL labs.
Site grade is A (IPv4), but for IPv6 no result …
Then I’ve test server again and I got this :
(x:xxx::xxx:xxxx:xxxx:8539): TLS handshake error: error:1408F10B:SSL routines:ssl3_get_record:wrong version number
In mean while I am trying to do debug link in Facebook debugger and I got this error
Curl error: 35 (SSL_CONNECT_ERROR)
Then I’ve created in subdomain new site and get a SSL Letsencrypt from Virtualmin.
Evertyhing was fine. I’ve checked in Facebook debbuger link, and it passed.
I’ve check in SSL labs and everythings fine.
It seems that from some reason SSL not reading IPv6 , i am not sure, but I suppose.
I would appreciate any help or guidance how to solve this issues
