Ok, your files work for me, thanks.
This you wont belive me probably -- I reproduced it many times:
It is
font related. Infact, letter related. Call me crazy...
The failing font is Quadraat regular and regular italic. Bold and bold italic work.
(It's a professional, original payware otf font, our corporate identity,
https://www.fontfont.com/fonts/quadraat)
It's about the letters
l, i, I: If the domain starts with one of these, the link fails.
If the domain starts with any other letter, even 1, the link works.
See the attached pdf.
It also has to do with Scribus itself somehow because if I use Quadraat in Word, then pdf Creator, the links are working. I can send the font privately if someone is interested in finding out what's happening exactly here.
I have no clue, but think it's about hidden spaces the font/Scribus uses for spacing somehow...?
Do you mark the threads as solved here?
