I've been banging my head trying to resolve this. Here is the problem and what I've done so far:
(1) I have domain: domain-one.com
(2) domain-one.com forwards to domain-two.com by .htaccess code below
############################
Redirect To Other Domain
############################
Options +SymLinksIfOwnerMatch
RewriteEngine on
RewriteRule (.*) http://www.domain-two.com/$1 [R=301,L]
(3) When attempting to access http://domain-one.com all is OK, forwards properly to domain-two.com, but
(4) When attempting to access https://domain-one.com, I receive SSL error "Your connection is not private" (this is Chrome's message)
The main problem I am facing is how can the https:// also forward from domain-one.com to domain-two.com without causing the "Your connection is not private." invalid SSL issue.
(5) Here is a breakdown of what is working and what is not with the .htaccess forwarder:
5.a FAIL: https://www.domain-one.com/ -> domain-two.com, "Your connection is not private."
5.b FAIL: https://domain-one.com/ -> domain-two.com, "Your connection is not private."
5.c PASS: http://www.domain-one.com/ -> domain-two.com
5.c PASS: http://domain-one.com/ -> domain-two.com
Excuse me for my ignorance and confusion on this. Thank you in advance for any tips on this problem. I am happy to provide any further clarifications needed, but I was trying to keep the post short.
