Hello guys,
we are facing a strange issue.
We have cas running on GCP
After starting our instance we can see this error in the logs
2022-10-14 10:56:39,178 INFO
[org.apereo.cas.configuration.DefaultCasConfigurationPropertiesSourceLocator]
- <Configuration files found at [/etc/cas/config] are [[file
[/etc/cas/config/cas.properties]]] under profile(s) [[standalone]]>
Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver
class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered
via the SPI and manual loading of the driver class is generally unnecessary.

If we push the previous build it works fine, but nothing has been changed
in the cas configuration, nothing on DB side. The only change contained in
the new build is something related to the frontend.
We test also network connection and it is fine.
Does anyone have any kind of suggestion ?
Bye
