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.
