curl: (7) Failed to connect

[Spearitch]

Hello

I am using Buildroot as distro on my STM32MP1. A colleague created a rest point to test if the MPU connects with the server:

when I:

curl -i -k -X POST -H "Content-Type: application/json" "URL"

I get :

HTTP/1.1 502 Bad Gateway
Date: Fri, 06 Nov 2020 14:05:01 GMT
Content-Type: application/json
Content-Length: 36
Connection: keep-alive
x-amzn-RequestId: a62c79be-416a-45f3-bb73-886dacefb038
x-amzn-ErrorType: InternalServerErrorException
x-amz-apigw-id: VlqyBGk9FiAFfOg=

Does someone have a solution ?


Thanks
