#68 Wrong XML namespace

[Anonymous]

I tried each Library to connect to my router but get various errors, e.g. when trying to connect with Cling this error is logged:

18:01:19.075 [cling-5] WARN o.f.c.b.xml.DeviceDescriptorBinder - Wrong XML namespace declared on root element: urn:dslforum-org:device-1-0

Any clues on what to try next?
