Problem with authentication after deployment

[LordCaca]

Hello everyone,

I create a application that uses QNetworkRequest and QNetworkAccessManager to do requests to an online API (JSON).

When I compile and tested it in the Qt Creator it works perfectly, but when I deployed it, the authetication of the login credentials don't work.

Again: the login work in Qt creator, but doesn't when deployed.

for deployment I used the cmd windeployqt.exe .

Where do your login credentials come from? A file?
Check if all paths are correct.

@Pl45m4 I use an online API, and while it's running in Qt Creator, the authetication runs perfectly.
the problem is when I open the .exe file and I got the error "Wrong User and password".

@LordCaca

That didn't answer my question :)

So you have your login credentials hard coded, are they coming from GUI or file?

[LordCaca]

@Pl45m4
From GUI.
This is the login screen:

If the login is succesful, I get this screen (this one is running from the Qt Creator):

But when I run the .exe file and enter the same credentials, I got (user and password incorrects):

online API

Is that a secure (HTTPS) URL you use to connect to?
If yes, it looks like you may have issues with the SSL handshake, probably issues with the OpenSSL libraries in PC you deployed your app.

Is it possible you can gather more details about the login process (any log??) and/or capture network traffic (i.e. Wireshak) to the endpoint?

@Pablo-J-Rogina I'll try to wireshark, but both tests were made in my own computer.

You didn't answer to that question...

[LordCaca]

@Pablo-J-Rogina sorry, yes it is. it's from heroku (if it's important)

if it's important

well, the idea is to confirm that the URL you're connecting to is using the HTTPS protocol.

And if so, it's likely you have an issue with the OpenSSL libraries not in the path in the scenario not working (when you "deploy" your application)

@Pablo-J-Rogina I solved the problem by coping some .dll files that qtdeploy didn't create. thanks for your time and help!

Great! for the sake of completeness, could you please list those files and where you placed them? Thanks.
