Hi,

Could you share us your OVS configuration?
Please send us the following information.

# OVS version
$ sudo ovs-vsctl --version

# Overview of OVSDB contents
$ sudo ovs-vsctl show


FYI, on my environment, I could run this application as following.

$ sudo mn --controller remote
*** Creating network
*** Adding controller
Unable to contact the remote controller at 127.0.0.1:6653
