Great to hear it’s working fine again Angelo! 
I get on all my local sites an “invalid ssl certificate” error/notice…
How can I fix this?
I’m wondering if you got “NET::ERR_CERT_INVALID” / “Your Connection is not private” message? and if you’re using Chrome browser (most recent/latest version)?
Have you tried to access the local site(s) with different browser (FireFox for example) and see if the site could be access just fine via HTTPS URL (and no error message)?
You may want to check this other thread about that Chrome browser issue - in case that’s the issue you may be experiencing.
Cheers,
Agus
