Hello again,
so I can´t find any limitations at my server.
I asked the support from the down-them-all-company.
This support answered that at your phoca download there is a bug with HTTP range.
If you download a file normally with the browser or other tools like wget and cut the download and resume it later
then the file is corrupt too.
I got a patch from the team of down-them-all for you.
Please read it carefully and give me a feedback.
Thank you very much!
Regards,
Kristin
Here the ranges-file:
Fix Request Range handling:
This patch might be correct, but is fully untested.
If you want to use this, then you must verify it actually works!
