Failed to resolve address

[muman613]

Hello,

I found this project useful to demonstrate connecting to a wifi ap... Unfortunately that is about all the code does at this time.

For me the part which tries to resolve the hostname to ipv4 address constantly fails. Here is the log:

getaddrinfo() fails with code 12 (not sure what it means). Has anyone else resolved this problem?

I believe I am using Zephyr tag v3.4.0-rc1 at the moment...

Thank you,
