network error when loading a fairly big report 33m function calls

[ioweb-gr]

I'm receiving the following error in console when loading a fairly big profile. After a few minutes this appears on chrome. Firefox runs the whole first step and shows the same error in step 2.

Is there something interesting in your http server logs or PHP/FPM logs ? For instance nginx closing the connection because a timeout is reached.

[ioweb-gr]

Sorry for the delay. I've tried in multiple attempts to find anything meaningful in the logs but unfortunately nothing appears that's meaningful. Just successful responses. I have set nginx timeout at 3600 seconds so it shouldn't cause any timeouts
