Hello Sir,
I wonder if your website has a valid security certificate, (make sure the certificate is well configured) otherways the https address will not work at all since that protocol is exclusive for certified websites where you can make online payments in a secure way.
About google adwords error, they don't allow you to publish adds in Google Adwords if your website does redirect to somewhere else (another website) it only Works with direct domain address.
SEO stuff doesn't affect your google campaings at all neither the https functions. and I supposed both copies of your website are hosteed in the same domain, so that's not a problema.
