The passenger seems to have some issues

[ltseng]

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？

That's probably because /tmp was full due to another user's software malfunctioning. Try again now.
