Their was a change concerning weblink, so I guess it might be related:

From my perspective, the problem is the FTP link.

FTP links are not allowed based on this code

Has this worked in 0.62.x?

@ReneNulschDE, yes, this has worked until 0.63 and you're right. When i remove the FTP Link it works again.
Why are ftp links not allowed?

sorry, looks like this was my mistake. I've changed the code from vol.Url() to cv.url with the latest commit. I'll create a PR to fix this.
