I ran a node application and turned off the Proxy mode in nginx settings. It was working normally until at some point it encountered an access error for 502. Then when I visited my website, it turned into returning an index page instead of the response that should have been returned by the node application. The log in the picture seems to indicate that the passenger did not start. How can I restore it to normal？

I run these commands just to check the results, because usually if there are control. log and exceptions, they will be output in the terminal. Because I could see the 'run script' button on Plesk, I thought it was feasible. I didn't know if these commands were the cause of the problem, and I hadn't done any research on because I couldn't see the currently running process, so I had to seek your help. By the way, "If I start a Node process that never ends on its own how do I stop it?"

It has been restored now, but as you can see from the picture, after I found that the usage was high and disabled the app, the peak still lasted for seven or eight hours. Isn't this a bit strange?

The Account Load always shows that the memory and CPU usage are very high，but I have stopped the node service and did not run other applications. I think it is a bug. Please help me solve it. You can reset my host if necessary. Thank you.
