            Hi,
            Win + r. and type “certmgr.msc”
            Then, delete 3 items :
            R3 Certificate and DST ROOT CA X3
            To delete, just win + r “certmgr.msc” then go thru :

            Trusted Root Certification Authorities > Certificates
            Intermediate Certification Authorities > Certificates
            Third-party root Certification Authorities > Certificates
            Right click, and press delete

            To locate the right certificate :
            Just use Issued By and Expiration Date, search for certificate issued by DST ROOT CA X3, and expired around 29-30 sept 2021.

            Install new certificate :
            Download this : https://letsencrypt.org/certs/isrgrootx1.der
            Double click it.
            Then, Choose Local Machine, Next
            Choose Place all Certificates in the following store, and then choose “Trusted Root Certification Authorities” folder
            Restart your PC
            Can find more ways to fix NET::ERR_CERT_DATE_INVALID error.

                Hey, that doesnt work for me.

                Any other Chromium Browser like edge or chrome has the "advanced" option to load the website anyway ignoring the outdated cert. Why not in opera?
