download demo can't work

[Август]

Hi

    I'm testing downloading a file from AWS S3 using ncs but it's not working well. I'm getting an error called -116 Connection timed out. 
    I also used another client to connect and it was not able to connect. I used the IP and port from the logs.

    Can you give me some advice, thanks.

ncs: ncs2.7.0
sample: v2.7.0\nrf\samples\net\download    only build and download

board: nRF7002-DK

Hi,

 

Q1: Is this issue repeatable on your side, or is the sample itself unstable?

Q2: Could you try to disable ipv6 to see if this issue still exists? this is done by setting CONFIG_NET_IPV6=n and compile/flash again.

Q3: Have you checked that you can access this specific website on your network in general? Ie. that it is not a firewall that is blocking the connection?

 

Kind regards,

Håkon

Yes，this issue repeatable on my side 100%

Q2: Could you try to disable ipv6 to see if this issue still exists? this is done by setting CONFIG_NET_IPV6=n and compile/flash again.

OK， I will do it.

Q3: Have you checked that you can access this specific website on your network in general? Ie. that it is not a firewall that is blocking the connection?

I can open it.

It also can't work，Do I need to renew my certificate?

Hi,

 

The certificate shall be loaded upon boot.

For debugging purposes, could you try to add a couple of seconds delay in this line?

https://github.com/nrfconnect/sdk-nrf/blob/main/samples/net/download/src/main.c#L304

 

ie. a k_msleep(5000); for instance, before the download starts.

 

Kind regards,

Håkon

Hi,

  Thanks for your response. I tried your method, but it didn't work.

  I personally feel like there is something wrong with the configuration, because there is no problem using our URL. So I think something like certificate or user name password need config. 

  Can you try this example? I believe you will also be able to reproduce the problem. Thanks.

Hi,

 

That is also using the amazon root CA, so there should not be a problem with the certificate chain.

This worked on my end (please note: I have no ipv6 connectivity at my end):
