The AUT is in their private networkUse Tunnel
  • Tunnel Manager and Tunnel Server endpoints
  • Allow QUIC / UDP on port 2345
AUT is behind a firewall (but publicly accessible)

There are 2 solutions, pick one of them:

  • Whitelist our NAT Gateway public IP addresses
  • Use Tunnel and whitelist the Tunnel Server hostnames.
  • NAT Gateway IP addresses
  • Tunnel endpoints
Note:

In case your network still receives connection refused due to insufficient IP whitelist, you can reach out to the Katalon support team.
