Promblems with network not allowing PortMapper

[Bluelight82]

I used PortMapper 2.1.1 fine a few weeks ago, and nothing has changed network wise that I know of, but now I suddenly get this error: INFO Creating router factory for class org.chris.portmapper.router.cling.ClingRouterFactory INFO Searching for routers... INFO >>> Starting UPnP service...

Did the ISP change something in the router? I used the first UPnP librarybefore, that gives and error now. I can select the third library option but it gets stuck when Editing and creating presets, and after a long time it tells me that it was not possible to find localhost IP or something. Could it be a Firewall issue?

It is not a firewall issue! Just tested every possible combinations of disabling firewall and anti-virus.

Did you get this message before: Failed to set modified URLStreamHandlerFactory in this environment. Can't use bundled default client based on HTTPURLConnection, see manual.?

This could be caused by the Cling library in StreamClientImpl.

Did you change anything in your environment, e.g. install a new Java version?

You could try two things:

• Deactivate the relevant Cling code by starting PortMapper with java -DhackStreamHandlerProperty=done -jar portmapper.jar. But this might cause other issues.
• Use another UPnP library included in PortMapper.

Closing as stale.
