Error occurred while running RTO consumer - Failed to request service discovery information.

Hi,
I am using RTSDK for streaming real time prices but I get below error when I run my consumer. I am using Authentication version v2. I am able to successfully login using the curl command. I have required licenses also in place under my service account. Can you help why the failure. Is it something related to license where license does not have all the scope assigned. Adding code snippets for more details. TIA

Hello @anna.h

Does your machine network policy/firewall block a connection to the RTO server?

You can try with the telnet command from the same machine that encountered the issue as follow:

telnet ap-southeast-1-aws-3-sm.optimized-pricing-api.refinitiv.net 14002

If the connect success, it should show the following empty prompt like this.

Hi @anna.h ,

Based on your description and the error message, it would appear that the licences attached to your MachineID have been changed or expired.

Are you on a trial account or full production account?

If this is for a full Production account, I recommend you raise a ticket with MyAccount for the RTO service

If, however, you are on a Trial account, then please speak to your Refinitiv account representative to discuss extending the trial or other options.

anna.h

Thanks for the quick response. I am on a trial account. I checked the license details and it's start date is today and it ends one month from now.

The account is valid but it doesn't have the trapi.streaming.pricing.read scope which is required when requesint the real-time streaming data.

Please contact your LSEG account team or sales team to verify the permission.

The previous error seems to have got resolved. I am able to get all the locations using curl (https://api.refinitiv.com/streaming/pricing/v1/) but only via cmd.

When I run my code I get below error. Can you help here please.

To scope down the issue, please run the ex113_MP_SessionMgmt or ex450_MP_QueryServiceDiscovery example in the package. Please also confirm the version of RTSDK or EMA that you are using.

Moreover, we need trace log to verify what the problem is. Please check this Learn how to direct EMA Java log to Java Logging API article.

I am using version: '3.8.0.0'.

I can discover all the Url’s using my code, but I am not able to connect to any of the discovered AWS url’s as I keep getting timeout error for all locations.

Do I need something to be able to connect to the aws url’s. Is it something related to certificates or some other access that I need.

TIA

Thanks for the response. I am currently working with my Info Sec team to get the port 14002 opened for the *.refinitv.net domain
