• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

We have a bunch of servers on both Onyx (17) and Obsidian (18) on CentOS 7 that have begun logging entries like this in syslog:

wdcollect: Failed to connect to database server: SQLSTATE[HY000] [1045] Access denied for user 'admin'@'localhost' (using password: YES)

sw-engine-pleskrun: PHP Warning: Error while sending QUERY packet. PID=2689; File: /usr/local/psa/admin/plib/vendor/plesk/zf1/library/Zend/Db/Statement/Pdo.php, Line: 22
wdcollect: PHP Warning: Error while sending QUERY packet. PID=2381 in /usr/local/psa/admin/plib/vendor/plesk/zendframework/library/Zend/Db/Statement/Pdo.php on line 228

Plesk is working fine, so I know the credentials in psa.shadow are fine, so I'm not sure why it's having that access denied issue. I did a plesk repair db and plesk repair mysql, then a reboot. That possibly corrects the first issue, but then we start seeing the second and third errors, every five minutes.

Watchdog seems to still be working, so the error makes no sense.

Any ideas?
