Jenkins setup: Version 2.440.2 / Ubuntu 22.04.3 LTS

I am receiving this error when trying to run my agent.jar file

```auto
Mar 30, 2024 6:35:20 PM hudson.remoting.Launcher$CuiListener status
INFO: Locating server among [https://snm-cloud.site:8443/]
Mar 30, 2024 6:35:20 PM hudson.remoting.Launcher$CuiListener status
INFO: Could not locate server among [https://snm-cloud.site:8443/]; waiting 10 seconds before retry

```

Does anyone know why this error would get thrown?

**Could not locate server among**

@smeghoo I was wondering if the answer from Norbert solved your problem.
