General issue report

We run rainmaker in a private AWS instance. OTA was working fine a few months ago. Now i am trying to update a few nodes and in the console i get the following:

Any ideas on how to dig deeper in the problem and fix the issue?

Can you try initialising the console commands using esp_rmaker_console_init() and check memory available after you see this error using mem-dump command on the serial terminal?

Also, please check if you can download the OTA image using the url from a host machine connected to the same network.
