      If the Let`s Encrypt Certificate in ISPmanager Has Stopped Automatically Renewing?

      If the automatic renewal of Let’s Encrypt certificates stops working, we recommend that you do the following:

      1. Download the file /usr/local/mgr5/lib/letsencrypt_lite.so
        Be sure to keep a copy of the original version of the file.
      2. Open the file in notepad ++ (UTF-8 encoding without BOM)
        Replace "https: //letsencrypt.org/documents/LE-SA-v1.1.1-Aug ..."
        to "https: //letsencrypt.org/documents/LE-SA-v1.2-Novem ..."
        Remove 1 "NUL" immediately after the .pdf (the new link is 1 character longer)
      3. Download the updated file.
      4. Reboot the server.
