Redirecting HTTP to HTTPS stopped working

If you click Advanced you should be able to get more info.

Are you sure you are having problems with redirecting, and not certificate problems? I ran a check of your site in SSL Labs. It says your certificate doesn’t match.

(abbreviated output)
SSL Report: www.coteseg.com
Certificate name mismatch
Try these other domain names (extracted from the certificates):

sslblindado.com
*.sslblindado.com
