Using multiple containers on different ports

[LaurenceBont]

Hi,

I was able to create multiple containers using different ports but R only accepts the default port (4003), all other ports R states "Error in if (curMsg == .twsIncomingMSG$ERR_MSG) { :
argument is of length zero"
while the container is active (it is listed in docker ps)

Also, I cannot connect to any other port using VNCViewer other than the default 5901. How can I view other containers that are not using the default ports?
