Error text Failed REST request from HTTP status code 400
Hello
My customer is evaluating Elektron Realtime-Optimized with EMA.
During subscribing data, sometimes get bellow error message
[08:48:41,943] WARN OmmConsumerImpl pool-3-thread-1 - loggerMsg
ClientName: ChannelCallbackClient
Severity: Warning
Text: Received Channel warning event on channel Channel_1
Instance Name Consumer_1_1
RsslReactor @6b066308
RsslChannel @5a3999d
Error Id 0
Internal sysError 0
Error Location Reactor.processWorkerEvent
Error text Failed REST request from HTTP status code 400 for user: GE-A-01377963-*.****. Text: {"error":"invalid_grant"}
loggerMsgEnd
Once the message is shown, the program will still continue to receive updates for those RICs that have been subscribed. However, new subscription will take around 10 seconds or more before it is succeeded (usually it is less than 100ms)
May we know any suspected cause of the above error message ?
Many thanks in advance
Best regards

This issue is most likely caused by an issue with RDP Authentication system being used by the RRTO service.
Please follow the instructions from the accepted answer of this post - to generate the HTTP REST message trace output.
You can then raise a My.Refinitiv ticket with the Refinitiv Real-Time optimized team to investigate why you are experiencing the intermittent failure - attaching the HTTP REST message output.
The REST message output will look something like shown in this post.
Please DO NOT upload trace with Client credentials to the forum.
