I am using a Huawei data-card to stream live video to a Wowza server, and over the last few days I have noticed my connection is being forcibly closed at around 900 seconds - consistently.

 

The connection is not idle, as 1Mbps of live video is passing over it.

 

Af first I suspected my Wowza server, however, opening an SSL connection to another server demonstrated the same 'remote end terminated connection' at 900 seconds.

 

So I switched to my Vodafone sim... no problems.

 

I switched to my Spark sim... again, no problems.

 

 

 

I tried the same test, using my iPhone X (which is on a 2degrees SIM - a different SIM to my initial test).

 

Guess what... remote disconnect at 900 seconds!!!

 

 

 

What's going on? Why is 2degrees terminating my TCP connections when they reach 900 seconds old?

 

 

 

Thanks
