High HTTP latency with PM2

I have a NestJS application running in docker with PM2 and it's extremely slow although it consumes very little resources. The reason is definitely not the traffic as there is nearly no traffic. When looking into PM2 Monitoring I see that the HTTP Latency is extremely high.

When running the same application locally I can't see any of this issues.

This is a snapshot of one of the clusters in PM2.

│ Heap Size 106.32 MiB │
│ Heap Usage 86.07 % │
│ Used Heap Size 91.51 MiB │
│ Active requests 0 │
│ Active handles 16 │
│ Event Loop Latency 0.61 ms │
│ Event Loop Latency p95 1.59 ms │
│ HTTP Mean Latency 2 ms │
│ HTTP P95 Latency 9752 ms │
│ HTTP 0 req/min │

Any ideas what I can change in the configuration or how I can investigate into this issue? I haven't found anything on this topic anywhere.

you can delete that app and restart , "pm2 delete app" and "pm2 start index.js". this form will clear that latency. this has happened with my application
