Hello, we currently have a t2.micro server on AWS with Ubuntu20 which contains bench 5.7.6, frappe v13.22. and erpnext 13.22.1. With this an accounting system has been created. Now, a constant problem arises and that is that connection is lost in specific networks, for example:
-In client A the connection is lost and does not load (for approximately 5-9 minutes), but in any other network (mobile data or external networks) it works correctly.
This happens on any network, whether it is your own, external or mobile data, but the point is that connection is lost on a certain network.
I share the nginx configuration.

I’m new with frappe and it’s a legacy app. Any comments would be very helpful.
