I have FINALLY found a solution to people with weird PCs that can’t accept the new SSL certificate my website has.
- Download lets-encrypt-x3-cross-signed.crt (1.6 KB)
- Open the file and hit “Install Certificate”
- Select “place all certificates in the following store” and hit Browse
- Select “Intermediate Certification Authorities” and hit “Ok”
- Hit “Finish”
- Use the script you were trying to use, now it should no longer error.
