Nginx+pm2 sometimes returns 404?

Question

Nginx

Hello!

• I have the following configuration: vps -> nginx -> pm2 -> expressjs
  
• However, about once a day, for a few seconds, nginx simply returns 404
  
• i.e. for a few seconds nginx can't reach expressjs
  
• server does not restart
  

Any ideas? Thank you!

Answer 1

See if there is a chronological pattern or a correlation with something else at the time of the manifestation of errors - high load, background processes, backups, increased traffic, etc. This happens with the same URLs or different ones, does someone touch these files ... In short, we need diagnostics.

No need for a picture. Pictures - damage))))))))
Yes, it's better to bang with an svg-shka.
Through css, you can use the mask via clip-path (but this is again a mask to draw in svg).
You can play around with border-radius. But not the fact that exactly the same result will be.
