  If you are running locally
  Try running without your firewall being enabled t test if the firewall is blocking mpi.
  Also, are you running with vpn ?

  Hi Geo.
  Thank you for your reply
  I tried the firewall and made sure mpi is an allowed app, it didn't work.
  .Yes, I am running with a VPN since my license is from my University and because of COVID I have to connect via VPN off-campus to activate my license.
  Is there any way to fix it with the VPN connection?
  Cheers Amir
