Run the following commands to reset the dynamic port range to what it should be and reboot - this should fix things until Windows messes up the dynamic port range again. This is only for ipv4. I haven't looked at ipv6, but I'd assume it's similar.

netsh int ipv4 set dynamicport tcp start=49152 num=16383
netsh int ipv4 set dynamicport udp start=49152 num=16383

 

 

 

 

 然后重启电脑即可解决。记得重启！重启！重启！
