Nginx load balancer edge group timeouts

[dmitry027]

Hello everyone,

I am trying to set up Ant Media cluster with Nginx as load balancer and noticed that config on the man page https://github.com/ant-media/Ant-Media-Server/wiki/Nginx-Load-Balancer contains the following settings for edge group:

proxy_connect_timeout 7d;
proxy_send_timeout 7d;
proxy_read_timeout 7d;

Could you please explain why we need these values to be so high? And if the values are correct, why they are set for edge group only?

We added those lines because of 504 errors. You can decrease them.

@Murat Eminoglu thank you for the reply. Could you please explain more detailed what are the conditions for this error to occur? And why we have these lines only for edge group, but not for origin?

These are the settings we used when testing 150K (reverse proxy timeout settings) Because of that added to only the edge side. I hope it 's clear now.

So you used these settings for stress testing and they are for extremely high load? Am I understand correct?
