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
