Read this: > **[DST Root CA X3 Certificate Expiration Problems and Fix](https://www.stephenwagner.com/2021/09/30/sophos-dst-root-ca-x3-expiration-problems-fix/)** > > Today, the DST Root CA X3 certificate expired, leaving many devices on the internet having issues connecting to services and certificates that use this Root CA, including those using Let’s Encrypt certificates. Some of these problematic devices... Download the root certs mentioned in the post Run mmc install the certificate addin in mmc, choose local machine install the 2 root certs in trusted root cert authorities Note that this is done in the windows 7 client. If you are the admin of the webserver that is affected then post the URL of the website and we can take a look at it. ---

I thought Windows 7 is End of Life and no longer officially by Microsoft, and thereby most of the rest of the communities as well. ❓ ---

Here is my general guidance for Windows 7 from [Let's Encrypt DST Root CA X3 expiry Sept 30th 2021 | Certify The Web Docs](https://docs.certifytheweb.com/docs/kb/kb-202109-letsencrypt#windows-pcs) > For Windows 7 (without outdated trust store) you should urgently replace the machine operating system with Windows 10 or higher. If this is not possible, manually install by browsing to [http://x1.i.lencr.org/](http://x1.i.lencr.org/) in order to download the .cer file for ISRG Root X1, open file, click "Install Certificate..", Choose default option "automatically select..", Next, Finish. The ISRG Root X1 certificate will now be visible using certmgr.msc under Trusted Root Certification Authorities. Reboot machine. ---
