Hello Erik,
do you by any chance know whether your previous version of Konqueror still 
used the WebKit engine or had it already switched to QtWebEngine? In the first 
case, I think you can have found yet another feature which stopped working 
with the switch to the new engine.

If your current Kubuntu version still provides KWebKitPart, you could also try 
installing it, select it as default web engine in the General tab of the 
Konqueror settings page and check whether the HTTP Authentication works with 
it. If it does, the problem lies with QtWebEngine, otherwise, we'll need to 
investigate somewhere else.
