Demo programs crashing with http error 401

[wp-xyz]

The demo projects "owm_demo" and "LazarusTreffen" are crashing with the exception "Unexpected response status code 401".

If using Lazarus within Linux, I "solved" this one by using xterm as launching app:
Lazarus menu: Run / run parameters.
Annoying, but it works..
