Issue Can't access Plesk panel NET::ERR_CERT_AUTHORITY_INVALID

[nayanaciuro]

Hello, I can't access the plesk panel of my website. It gives me error NET::ERR_CERT_AUTHORITY_INVALID as shown in image below and it happens in every browser.

I tried to access the plesk panel as: https://flamboyant-pascal.xx-xxx-xxx-xxx.plesk.page/ and https://mywebsite.com:8443/ but both won't work even tough it was working hours ago and I didn't make any change.

The website is working fine, the problem is with plesk panel. I wan't to know if this problem is temporary or if I need to do anything.

Thank you

This looks like a known problem. Have you checked KB article - A warning is shown while accessing Plesk or webmail: The certificate is not trusted or NET::ERR_CERT_AUTHORITY_INVALID ?

My sites just took a dump. It takes for ever just to even access Plesk! Not sure what's going on but all my sites are down hard. I'm looking for a solution here.

I think it might be happening due to the following reasons:
1. Expired or installed invalid SSL certificate
2. Misconfigured SSL certificate
3. System date and time discrepancies
