Closing connection 50 seconds - No response in between

Websocket API closes the connection. It never sends PING. Most of the times it doesn't even respond to Login.

What I do is:
- authenticate with https://api.edp.thomsonreuters.com/auth/oauth2/beta1/token to get an auth token
- fetch the services list from https://api.edp.thomsonreuters.com/streaming/pricing/v1/
- choose a websocket tr_json2 service and connect to it
- send Login request


Here's my logs. Timestamps show it's probably a connection timeout.

You are right, the example works.

I removed the authentication cookie and placed the access token in the Login message after socket is established and I got proper response and pings.

Hi @stefanos,

Great. I'm currently using the authentication cookie to login to the server. When you use the cookie, you don't need to send an explicit login message as well. I haven't actually tried to set the cookie and also send an explicit login but I would suspect it may produce unpredictable results. In either case, you will still need to send an explicit login to refresh your tokens.

That's 4 requests, the 3rd one actually got a Login response

Hi @stefanos,

Can you provide more details around how you are logging in? Are you sending an explicit login request after you connect? Or are you using the TREP Authentication feature where you set the authentication token details within a cookie when you connect?

One thing to rule out is to go through the quick start and run the example code to see if you notice similar behavior.

When I connect, I notice a Ping message every 15 seconds or so. Are you able to log all traffic coming into your onWebSocketMessage callback?

Hi @nick.zincone.1

Here's the details:

Handshake request headers: {Accept-Encoding=[gzip], Cache-Control=[no-cache], Connection=[Upgrade], Cookie=[AuthToken=*masked*;AuthPosition=127.0.1.1;applicationId=256;], Pragma=[no-cache], Sec-WebSocket-Extensions=[permessage-deflate], Sec-WebSocket-Key=[*masked*], Sec-WebSocket-Protocol=[tr_json2], Sec-WebSocket-Version=[13], Upgrade=[websocket], User-Agent=[Jetty/9.4.9.v20180320]} Handshake response headers: {Connection=[Upgrade], Sec-WebSocket-Accept=[*masked*], Sec-WebSocket-Extensions=[permessage-deflate], Sec-WebSocket-Protocol=[tr_json2], Upgrade=[websocket]}


I use the access_token I got from oauth as AuthToken

Handshake response headers: {Connection=[Upgrade], Sec-WebSocket-Accept=[*masked*], Sec-WebSocket-Extensions=[permessage-deflate], Sec-WebSocket-Protocol=[tr_json2], Upgrade=[websocket]}

When socket upgrades I send this:

{"Domain":"Login","ID":1,"Key":{"Elements":{"ApplicationId":"256","Position":"127.0.1.1"},"Name":"MyName"}}
