Your website

When visiting https://www.nestjs.com/ there is an SSL error.

You should either buy a valid cert for the www domain or fix your config to redirect to non www.

Didn't know where else to submit the issue

You're welcome :-)

Certificate seems fine.

Can you check whether your system clock is set correctly?

[AlexNodex]

Every other website I visit in the world with https:// works fine.

Checked it in Firefox and Chrome, in both cases the certificate is valid

[AlexNodex]

Chrome does a redirect back to the NON www tld which is why it works fine.

Chrome on iOS is not fine - see below screenshot.

Please note that the NON www domain IS FINE, anyone testing should make sure they're not being redirected.

Also see second screenshot from a curl command...

Yes, you are right. I used the NON www domain. The one with www does not work with Firefox and on Chroome i am redirected

It should work fine now :)
