- Plesk for Windows
Server backup finishes with warnings if there is a let's encrypt certificate installed:
[WARNING]: [e4dfb1b5-edcb-487b-bd12-d91e1a836b1f]: Unable to check existence of the file C:\Program Files (x86)\Plesk\var\modules\letsencrypt\etc\live\example.com\cert.pem. The file will not be archived. [:8449200]
Let's encrypt certificate is installed on a domain. This is Plesk bug with ID #PPPM-6126 which will be fixed in future updates.
As a workaround, apply a patched file:
1. Extract file
2. Backup file from the server by renaming it. The file can be found in its standard location:
3. Replace the backed up file with a patched one.
