Issue with subdomains


#1

Hi guys,

Thanks for letsencrypt !

It powers http://hackers.mu/. We are from Mauritius.

However, we have HTST issues with logan.hackers.mu and

selven.hackers.mu. and shaanxoryog.hackers.mu.

On firefox, people get this error:

This site uses HTTP Strict Transport Security (HSTS) to specify that

Firefox only connect to it securely. As a result, it is not possible

to add an exception for this certificate.

Can you please also whitelist the sub-domains ?

Kind regards,

Or temporarily disable HSTS. Note that removing the header won’t do that; you need to leave it in place but set the max-age to 0.
