Systemd service enabled but does not start - linux

I have a custom Spring Boot web application running on a Linux virtual machine. I have a systemd script to start/restart the application.
I have tried changing to WantedBy=default.target and it still does not work. I have tried adding After or Type and still does not work

x11vnc service failing with exit code

Thanks!
I am trying to setup x11vnc service on raspberry pi 4B platform, but it's failing. Below are the status logs:

Hint: Some lines were ellipsized, use -l to show in full.
Any suggestion on this will be really helpful.
I am expecting to enable x11vnc service on raspberry pi 4B.

RabbitMQ server won't start anymore after assigning username/password

I installed a rabbitmq server and it was active and running fine until I entered:
echo "[{loopback_users, []}]}]." > /etc/rabbitmq/rabbitmq.config
I also assigned a username and password and also assigned the user as administrator. I tried to restart the server after that and it wouldn't restart. Checked the status and it was no longer running. Any idea what I did wrong? Still a rookie, any tips would be great.

I'm sure the answer is right in front of me but I can't seem to pin point it.
please use the new format file config:
https://github.com/rabbitmq/rabbitmq-server/blob/v3.8.x/deps/rabbit/docs/rabbitmq.conf.example
## Related doc guide: https://rabbitmq.com/access-control.html.
## The default "guest" user is only permitted to access the server
## via a loopback interface (e.g. localhost).

Systemd does not activate service?

I need to leave a service on systemd running because it doesn't activate? For what reason this happens since I follow the recommendation of the documentation, below are the codes:
Code of the Service :

The ExecStart should be the command to be executed:
systemd manpages:
ExecStart=
Commands with their arguments that are executed when this service is started.
This stanza:
ExecStart=/usr/local/bin/python3.9 /var/net/
Should be:
ExecStart=/usr/local/bin/python3.9 path_to_python_script.py

kindly check the source list, in your source list might be something that disables the SSH
kindly use the different source list
Kindly change your /etc/apt/source.list to this Link it might work.

Can't set "max connections" - parameter of memcached higher than 4096 (exited status 71)

My start parameter for memcached are:
-m 900 -p 11211 -t 5 -l 127.0.0.1 -r 200000 -c 4096
If "-c" (max connections) is more than 4096, memcached won't start.

Does someone know what could cause these problem?
