I can not upload video via FTP

[ANTON KHUTTER]

Unable to establish a connection to the server. I am using FileZilla 11 and Cyberduck4 on a poppy. I tried everything, but it writes a server error

Check your router settings - if you have one. This can sometimes cause problems.

This is strange, but ftp to load on other drains works

So if I read you correctly, other ftp sites work fine and you only have problems with Adobe stock? 

What is the exact error you get. You can post an edited log file, where you edited out all your private data.
