@JonB thank you so much

@SGaist Yeah I ended up setting environment variables to point to the OpenSSL install inside of Qt. That ended up solving my problems.

@mzimmers If i iterate over the interfaces like in your script, then it works with no problem :)
Running on windows :)

When using only the QHostAddress::Broadcast I get the wrong broadcast addr. I too think it is strange, but this is no issue for me, as it's always simple to determine the right address by code or manually :) just strange as you say :)

Anways, off to new issues :D

@aha_1980 said in UDP Socket - writeDatagram uses IPv6 and not IPv4:

Then why not use QHostAddress::AnyIPv4 ? Looks more clear to me...

Learn something new everyday :)

@ambershark Thank you very much for your help, now it's working, it seems like I was passing the IP argument incorrectly, now I know that I have to send this parameter inside a QT function. thanks!
