Unraid - APPLICATION FAILED TO START "The Tomcat connector configured to listen on port 8080 failed to start. "

[PrzemekSkw]

Hello, I want to try new docker template on my unraid server.

I download configuration.yml to /mnt/user/appdata/Monitee-agent/ folder and put user/password. After I start container I get that in logs:

APPLICATION FAILED TO START
***************************

Description:

The Tomcat connector configured to listen on port 8080 failed to start. The port may already be in use or the connector may be misconfigured.

Action:

Verify the connector's configuration, identify and stop any process that's listening on port 8080, or configure this application to listen on another port.

Regards.

Do you have another container on the "Host" Network that already listens to 8080 or 8443?

Do you have another container on the "Host" Network that already listens to 8080 or 8443?

Yes, I have. Do I need to add ports variables to that docker template? Regards.

[hndrkx]

In the application.properties change:

# Application ports
http.port=8080
server.port=8443

See here: https://monitee.app/unraid/

[PrzemekSkw]

See here: https://monitee.app/unraid/

Thank You very much. It works now.

Regards.

[Krillsson]

thanks @hndrkx. I have updated https://monitee.app/unraid/ with a big warning box about this.

I also see that the template erroneously have default paths for the /config + /data. That has also been updated.

[Krillsson]

Will reopen this for visibility for anyone else running into the problem. See @hndrkx solution:

In the application.properties change:

# Application ports
http.port=8080
server.port=8443

Thanks. It create .../appdata/docker/data folder. Can I delete it and create /data in /Monitee-agent folder next to /config?

[Krillsson]

Yes, create /mnt/appdata/Monitee-agent/data

Copy stuff from the wrong directory into it

Then delete the wrong directory

Lastly, edit the container to point to the right directory in unRAID ui

Hi, I noticed that create folder:

to be sure, I need only /data? Not sys-api/data?

[PrzemekSkw]

Another question. I don't see logs in Monitee-app on smartphone. Can I change default variable /vat/log for /mnt/user/Syslog?

[Krillsson]

Yes, create /mnt/appdata/Monitee-agent/data Copy stuff from the wrong directory into it Then delete the wrong directory Lastly, edit the container to point to the right directory in unRAID ui

✅ Correct directory

🛑 Wrong directory - delete

Make sure your config looks like this

I replied to your question in #186 so that its easy for others to find
