Error Resolution When Connecting to RTO Specifying RIC and FID

When attempting to connect to RTO by specifying RIC and FID, the following error occurred. Could this be due to incorrect specification of parameters passed to the consumer, or is it caused by something else, such as connection settings?

Hello @soichirok

The error message connection denied and login failed (timed out after waiting 45000 milliseconds) for localhost:14002) indicate that the application is unable to connect to the RTO servers.

Is you app behind a corporate proxy? Are you able to try it from a machine which has direct connection to the internet?

I would suggest that you try the EMA Service Discovery example and get it working, before trying to code your own application.

Your EMA configurations may be incorrect. According to the log, it uses the Consumer_1 and Channel_1 to establish a connection and it connects to localhost:14002 which is not the RTO server.

Therefore, you need to check the configurations. For example, the EMA sample configurations use the Consumer_4 and Channel_4 to connect to RTO.
