Problem with deploying Geoserver in Ubuntu+Nginx+Tomcat

I am having trouble with deploying Geoserver in my remote server running Ubuntu 18.04, nginx and tomcat10. In the past, I had successfully deployed Geoserver again and now, somehow, all hell is loose. I tried cleaning all tomcat instances, services and folders as well as geoserver folder. Then, I followed the instructions here and successfully installed Tomcat 10.0.12. However, Geoserver is not deployed at all, trying the respective url. My Catalina log shows this:

Can anyone guide me to what is wrong with the setup?
