SSL Error after migration

[11abbidoa]

We restored the Nagios data from the old server (CentOS7) to this new server (CentOS9).
We only reused the old server IP so to will be easier for us to replace the Nagios server.
However, some servers are now throwing an error related to SSL Handshake.

Example:
CHECK_NRPE: (ssl_err != 5) Error - Could not complete SSL handshake with 10.xx.xx.xx: 1
