Quick answer: For NP-37614-1 during Share Play, check PlayStation service status, update both PS4 consoles, test each internet connection, power-cycle both consoles and routers, then create a fresh party and Share Play session. A different network is the safest diagnostic for NAT or ISP issues.
Before you start
- Both players online and signed into PSN
- Current PS4 system software on both consoles
- Stable connections for both host and visitor
Steps to fix the error
- Check PlayStation services. If gaming, social, or account services are degraded, wait for recovery.
- Update both PS4 consoles. Each player should install the current system software and restart.
- Test both connections. On each PS4, go to Settings > Network > Test Internet Connection. Share Play depends on both sides, not only the host.
- Restart the connection path. Turn off both consoles and power-cycle each modem/router. Wait a few minutes before reconnecting.
- Create a fresh session. Leave the existing party, create a new party, and start Share Play again. Confirm that the intended player is host and visitor.
- Reduce connection strain. Pause large downloads and streaming on both networks. If possible, use wired Ethernet.
- Test a different network. A brief mobile-hotspot or alternate-network test can reveal whether a home router or ISP path is blocking the peer connection. Return to the normal network afterward.
- Escalate router changes. Do not blindly change ports, DMZ, or UPnP. Ask the router vendor or ISP to review NAT and peer-to-peer connectivity, and keep a record so changes can be undone.
Why this works
Share Play is a live peer connection involving two consoles and two networks. A clean session plus connection tests isolates service outages, stale sessions, bandwidth contention, and router/ISP path problems.
Safe alternatives
- Have the other player host a test session.
- Lower Share Play video quality when the option is available and the connection is unstable.
Warnings and limitations
Captions remained unavailable after every required retry. Viewer reports often mention router UPnP, but enabling UPnP changes network exposure and is router-specific. This guide treats it as an ISP/router-vendor decision, not a guaranteed fix.
Frequently asked questions
Is NP-37614-1 caused by the host or visitor?
Either side can be responsible, which is why both connections must be tested.
Should I put the PS4 in a DMZ?
No. That exposes the console more broadly than needed and is not a safe first-line fix.
Why try another network?
It is a reversible diagnostic: if Share Play works elsewhere, the original router or ISP path needs attention.
