WebSocket server stops sending data to client after a time

Hi,
We have data receive problem from Reuters WebSocket server after a while.
While we are getting prices from the server normally, after a time, it stops to send both the prices and PING message to our client side. So we are encountering idle connection case and also data loss case!
We have used 2 different WebSocket libraries and encountered with the same case. I have shared all the details below.
Dou you have any suggestions to solve this problem?
Best Regards.

Environment #1:
Uses Library: nv-websocket-client <=== This WebSocket library is used at Refinitiv github examples
In this test when we have detected that server did not send PING message for 30 seconds we disconnected from the server programmatically.
On login, we got pingTimeout is 30 seconds:
0531-110858.889-I-(WebSocketSession) - WSOCK: Handling login response on message:{"ID":1,"Type":"Refresh","Domain":"Login","Key":{"Name":"AQIC5wM2LY4SfczaaZd9CSZ7rS3ip37O4qx6l8Zg76TPSZY%3D%40AAJTSQACMTAAAlNLABMyMTU0MDE1NDg0MDk3NDc3MTc1AAJTMQACMjc%3D%23","Elements":{"AllowSuspectData":1,"ApplicationId":"256","ApplicationName":"ADS","AuthenticationErrorCode":0,"AuthenticationErrorText":{"Type":"AsciiString","Data":null},"AuthenticationTTReissue":1622459487,"Position":"10.57.5.20","ProvidePermissionExpressions":1,"ProvidePermissionProfile":0,"SingleOpen":1,"Su

We periodically got PING messages from server and answering with PONG message (generally getting PING messages in 20 seconds).
But after a while we cannot get either prices or PING messages from server:
0531-120818.206-I-(WebSocketSession) - WSOCK: Sending Pong message ß PING RECEIVED AND WE RESPONDED WITH PONG

// after then we do not get either any prices or PING message!
At 12:09:09 we detected that server did not send any PING message more than 30 seconds. So we disconnected connection and reconnected.
So here there is data loss due to server not sending prices until we reconnect.

Hi,
We have detected that the problem is ISP related. They have defined some rules and solved.
Thanks for the supports.

Hello @bilgisayarmuhendisi.tr,
It would be helpful to find out more, in order to understand the issue better.
Are you connecting via websocket to Real Time Optimized service , Refinitiv hosted, or local deployed infrastructure?
Are you testing with a Refinitiv example? Which one? If not, what language?
Depending on your answers, I would first verify the issue with Refinitiv starter example for this type of infra connectivity and preferably, the same language option.

Hello @zoya faberov,

Hello @bilgisayarmuhendisi.tr,
I did a quick sanity check on my side:
- Downloaded the latest version of MarketPriceRdpGwServiceDiscovery example.
- Built via ant, per README
- Created project with libraries pulled by ant->build and run for 5 mins ( I could have run command line, just personally prefer IDE)
- On my side it runs without disconnects
Would suggest to try the same test in your environment, use example MarketPriceRdpGwServiceDiscovery as is for testing, without any changes, with libraries pulled by ant build, to see if that would face the same issue. This should allow to determine, if the issue you observe is environment-specific, or code+websocket library related.

I think @zoya faberov suggestion is good to test to see if you observe the same behavior. This example is designed for a small use case to confirm expected behavior. However, if you are using a larger watchlist, there are some things you need to consider. Specifically, the larger watchlist of items, the more processing your application may take in post-processing. The more overall time spent in post-processing, the less time spent on processing update messages from the network. What we typically refer to as "slow consumer", what could be happening is the "ping" messages are being sent out in the expected time but are queued up on the network. The longer you take in your processing callbacks, the longer it takes to process messages from the network.
This is a possible reason that should be considered.

Hello @zoya faberov,
Sorry for late response.
I have tested our client app without the corporate proxy (we must use it on production) and saw that everything was ok. So we are investigating the problem on firewall side now.
Thanks for your help.

We just use 2 currency as subscription. We receive 4 or 5 currency value in a second as max. So we do not expect any slowness problem.
The problem is not receiving any message after 1 hour everytime. So our suspection is on our network rules. WebSocket (ws://) connection may be considered differently from the other http, https rules. We are still investigating.
Thanks.
