Question

Redirect https www subdomain to https non-www subdomain

Hey all,

I have a problem with redirect on my nginx server.

I have bought a wildcard ssl for my domain (example.com).

My problem is with a redirection from https://www.subdomain.example.com to https://subdomain.example.com .

Does someone have an idea how this can be accomplished ?

Thanks, Atanas

The cert is for *. example.com

When visiting https://subdomain.example.com everything is good. When visiting it with https://www.sub.example.com I got invalid certificate error before redirect.

Assuming the cert is for *.example.com or *.subdomain.example.com, the problem would be in your redirect rule. Include the relevant block from your nginx config. You’re also vague about what the actual problem is: is it not redirecting? Is the cert showing as invalid? Invalid on both, or only one? Invalid only after redirect?

Hi @atanaskrangov

You certificate is only valid for *.example.com not *.sub.example.com. You need to buy another certificate for sub-sub domains - or use the free Let’s Encrypt in that case.
