The requested fingerprint can be seen in %plesk_dir%adminlogsphp_error.log with debug mode enabled:

23892:61692e61c3f54 DEBUG [panel] Add virtual host example.com, site configuration XML:
[domain name="example.com" displayName="example.com" webspaceName="example.com" status="active"][webSql enabled="false"/][webmail type="none" *sslCertHash="5abbe6638348a67e9f80acf92cc973a0a2017cfc"*/]

However, no certificates with this fingerprint exist in the MMC Certificate Snap-in list in Windows.

Cause

Plesk is trying to secure new domains with an outdated Let's Encrypt certificate - the requested SHA-1 fingerprint does not exist in the certificate pool.

This behavior is caused by either a filesystem or a database inconsistency.

Resolution

Apply one of the following solutions:

Remove the inconsistent certificate

1. Connect to the server via RDP

2. Start a command prompt as an Administrator.

3. Connect to the Plesk database:

plesk db

4. Identify the filenames for the default certificate - there can be several of them:

select cert_file from certificates where name = 'Lets Encrypt certificate';
+-------------+
| cert_file |
+-------------+
| scf74AE.tmp |
+-------------+
1 row in set (0.118 sec)

5. Rename or move the found files from the %plesk_dir%varcertificates directory

6. Run the following command to reconfigure certificates:

plesk repair --reconfigure-ssl-certificates
