Hello,

For some files that I would like to download, I get this error message:
Use IPv4 to access this service!
In Windows 7, IPv4 and IPv6 are enabled and the router is connected to both. The error occurs at chrome and firefox on. I think,
this has nothing to do with the browsers. What could this be?

addendum:
If you deactivate IPv6 in the Windows network setting, then the download goes.
