Jenkins nginx timeout

[Mohamed Sadok Ben Jazia]

Hello list,
I'm running jenkins with nginx and everything works well.
However, When sometimes i open a project in jenkins admin panel, i get a 504 timeout error.
I didn't got any error in jenkins logs but in nginx logs
 upstream timed out (110: Connection timed out) while reading response header from upstream, client: myIP, server: jenkins.server.com, request: "GET /job/WebDevelopment/ HTTP/1.1
Anyone knows how to deal with
Thank you

Something to add,
The server consumes a lot of CPU, it reachs 80% of 4CPU while loading the project page the the load stops after showing the 504 timeout error
