The official Parsec documentation describes error codes and its close relative -6024 as occurring when the software is "Unable to Negotiate a Successful Connection" . This message appears when some network obstacle prevents the two computers from "seeing" and connecting to each other directly, causing the negotiation phase of the connection to fail.
Enforcing standard VPN tunnels can force routing traffic through a clean, unrestrictive remote server.
Traffic passes through two layered routers before hitting the internet.
Log into your router's administration page (usually 192.168.1.1 or 192.168.0.1 in a browser). Locate the or WAN settings. Ensure UPnP is enabled. 5. Port Forwarding (If UPnP Fails)

Type "Allow an app through Windows Firewall" in your Windows search bar. Click .
If UPnP is disabled for security reasons, you must manually forward ports to your host PC's static local IP address:

Plug the host computer directly into the primary gateway (the device connected to the wall outlet) via Ethernet. The official Parsec documentation describes error codes and
Parsec Error 6023 indicates a failure to negotiate a successful peer-to-peer (P2P) network connection between the host and client computers

In the technical world, Error 6023 is a failure of the "handshake"—a moment where two routers try to find a door to talk through and find only brick walls. It was a "Double NAT" nightmare. Elias’s router was screaming for a connection, but his ISP’s restrictive firewall was slamming the door shut.
Before changing advanced networking configurations, perform these basic troubleshooting steps on :
