How to run the script on VPS correctly?

Question

linux

Good evening, there is a vps server with ubuntu 20.04 on it. Two python scripts are running on the server 24/7. But they only work when I'm in an ssh session with a vps (ssh client - mobachterm). As soon as I exit the server the scripts stop working.
That is, I go to the server, run the scripts, and until I left the server, the scripts work.
Notes:

• I put scripts in bg%
  
• scripts log about their start / end, and I know exactly at what moment they take off
  

UPD: a little about the script. Makes a bunch of requests via curl and requests, parses csv, logs, saves data to the database, sends letters to mail and telegrams. Maybe it has some meaning.

Answer 1

the easiest way to run with nohup (nohup /there/is/path/to/your/script &)
the correct way is to set up services to run and control your scripts. https://habr.com/ru/company/southbridge/blog/255845/

Answer 2

man tmux
