Hi,

for your information:

IoT Creators platform (SCS) times out the message forwarding POST request to the application URL if the application doesn’t response within 5 seconds.

In case of timeout SCS tries to re-POST the message 5 times. Every minute one retry is performed.

While the systems trys to re-send the message no new messages are POSTed to the application. There are queued.

Hi,

many users ask via which IP address IoT Creators SCS forwards received uplink messages to the registered application callback URL:

IoT Creators SCS forwards the uplink messages to your application callback URL via one of the two IPs

18.195.119.162 18.195.17.174

Hope this helps you to configure the IP whitelists of your application.

Regards, Roland
