ABB RWS Error Code 503 Issue

Hello,

I have developed an API using the ABB RWS service to collect data from the robot. However, I have noticed that I can only send requests every 6 seconds. When I reduce the delay below 6 seconds, I receive a 503 Service Unavailable error.

Is there any way to reduce this delay? How can I send API requests more frequently without triggering the 503 error?

Test Results:
---Delay 1000ms
