However, the community has identified three "flavors" of this error:
[Remote Client] ---> (Internet) ---> [Router Public Port 8000] ---> [Host PC Local IP: 8000] 3. Eliminating Double NAT Scenarios
A: In rare cases, your ISP may be actively blocking Parsec’s traffic. Try:
When automated protocols fail, manual static port forwarding binds traffic explicitly to your target device. Configuration Parameter Required Value / Setting Parsec Host Protocol External/Public Port Range 8000 - 8002 Internal/Private Port Range 8000 - 8002 Device IP Address Your host PC's static local IP address 6023 parsec error exclusive
This disables the first router's internal firewall, handing all routing duties directly to your secondary performance router. Phase 3: CGNAT and Enterprise Firewalls
If UPnP fails or is disabled for security reasons, you must explicitly tell your router where to send incoming Parsec data packages.
What are running on both your host and client machines? Who is your Internet Service Provider (ISP) ? However, the community has identified three "flavors" of
What router brand are you using?
Apple's modern desktop operating systems isolate applications from the local subnet by default. Open on your Mac. Navigate to Privacy & Security > Local Network . Toggle the switch next to Parsec to On . Phase 2: Advanced Router and NAT Engineering
Manual port forwarding is the most reliable fix, especially for double‑NAT or CGNAT environments. Parsec uses UDP ports in the . Configuration Parameter Required Value / Setting Parsec Host
Find in the list and ensure both Private and Public checkboxes are ticked.
Error code -6023 indicates that between the host (the computer you want to control) and the client (the device you’re using to connect).
Parsec Error Code 6023 is a network connectivity error that occurs when the Parsec client attempts to establish a peer-to-peer (P2P) connection but fails to negotiate the handshake. This error typically presents the user with a message indicating a connection failure or a timeout. It is most commonly triggered by Network Address Translation (NAT) configurations, firewall restrictions, or internet service provider (ISP) limitations.
