ORDS error message when only specifing IP/ords - But only after startup, once primed works fine

[GasparYYC]

Hi The IP address of my server is xxx.xxx.xxx.xxx. If I attempt to go to: http://xxx.xxx.xxx.xxx/ords (excluding /f?p=4550 from the URL), the page simply outputs:

ORACLE REST DATA SERVICES 503 Service Unavailable

The connection pool named: apex is not correctly configured, due to the following error(s): Unable to start the Universal Connection Pool: oracle.ucp.UniversalConnectionPoolException: Error during pool creation in Universal Connection Pool Manager: oracle.ucp.UniversalConnectionPoolException: Universal Connection Pool already exists in the Universal Connection Pool Manager. Universal Connection Pool cannot be added to the Universal Connection Pool Manager

I noticed errors in the startup log:

The interesting part is that if I "kickstart it" but including the "f?p=4550" part of the arguments then I see the login screen (meaning worked fine), after this point it woks fine if I only do: xxx.xxx.xxx.xxx/ords

In summary: it works after being primed by providing the argument.

Thanks
