Suddenly I no longer have access to these ports. nothing has changed, computers , network router etc. But, when I try and access the ports they are not available. No amount of tinkering with port forwarding will free them up. Unless I can do this then I can no longer use LR, so it is vital I find some way. I have tried all sorts of things like port checkers and route tracers, none help. I have tried firewalls as well.Has anyone any ideas as to how I can rectify the problem please?
