There really problem on my computer 1.
I have tried my computer 2 “set 2 instance at the same time” it work perfectly but in my computer 1 if i have “set 2 instance at the same time” problem will occur. it will say queue limit.
Note: Computer 1 and Computer 2 has different internet gateway/provider.
The two pc has different ip address and different internet providers. pc one got different locations and pd two same different locations. why my pc one got no problem at all i set it “2 instance at the same time” no error queue limit i set random gateway in manager. for the pc two problem occurs same settings. I wonder why.
