Your web server redirect is misconfigured: $ curl -I http://talloc.samba.org HTTP/1.1 302 Found Date: Thu, 15 Sep 2016 09:07:29 GMT Server: Apache Strict-Transport-Security: max-age=15552000; includeSubDomains;preload Public-Key-Pins: max-age=36000; pin-sha256="WGJkyYjx1QMdMe0UqlyOKXtydPDVrk7sl2fV+nNm1r4=";pin-sha256="kb6xLprt35abNnSn74my4Dkfya9arbk5zN5a60YzuqE=";pin-sha256="YLh1dUR9y6Kja30RrAn7JKnbQG/uEtLMkBgFF2Fuihg=";pin-sha256="Vjs8r4z+80wjNcr1YKepWQboSIRi63WsWXhIMN+eWys="; Location: https://talloc.samba.orghttps://talloc.samba.org/talloc/doc/html/index.html Content-Type: text/html; charset=iso-8859-1 That should be: Location: https://talloc.samba.org/talloc/doc/html/index.html
Seems OK now.
Doesn't look like it's fixed: $ curl -I http://talloc.samba.org HTTP/1.1 301 Moved Permanently Date: Thu, 20 Jun 2019 03:34:08 GMT Server: Apache Referrer-Policy: strict-origin Strict-Transport-Security: max-age=15552000; includeSubDomains;preload Location: https://talloc.samba.orghttps://talloc.samba.org/talloc/doc/html/index.html Content-Type: text/html; charset=iso-8859-1
but now fixed. Thanks for reporting and insisting!
