`dfx canister call backend get_payload_from_my_server `

return:

Given that IPv6 is required for HTTP outcalls, I would guess that’s why it fails with `1.2.3.4`. However, based on your stack trace, it also seems the SSL certificate is not recognized for your call.

Yes. i use self ssl certification:

this cmd can get respon.body data :  
wget -v -O- https://\<a\_ip\_v4\_addr\>:8002/file/file/ret\_to\_res\_body/  
payload\_02.json --no-check-certificate

The higher problem is that i actually want to send a file to my rust canister on ic.  
Only get this solution yet. If there is any better way will be great.

Don’t know about your use case, just wanted to shared the above information given it seemed related to the error you were facing.

Gotcha. Funny enough it’s the same approach I had to implement in my “Juno \<\> OpenAI” demo to pass a file to the Vision Preview API.

Great to hear you solved it!
