What is Ubisoft error code 8 0x00003700 in Rainbow Six Siege?

The ‘error code 8-0x00003700‘ message in Rainbow Six Siege indicates a lost connection between the player‘s game client and Ubisoft‘s game servers. Specifically, it means the Rainbow Six Siege servers are unreachable from that player‘s end.

This connectivity error prevents access to online multiplayer matches and blocks all server-dependent functionality.

Root Causes

Error code 8-0x00003700 has two primary triggers:

1. Server Infrastructure Issues

Intermittent outages or instability in Rainbow Six Siege‘s server infrastructure can cause the 8-0x00003700 error for a subset of players.

According to Ubisoft‘s latest figures, Rainbow Six Siege averages over 2 million daily players worldwide. Even rare server hiccups disrupt connectivity for thousands of concurrent users.

Most server issues self-resolve within hours, after Ubisoft engineers troubleshoot and restart affected data center hardware. Various forum posts indicate that server problems trigger upto 30% of all 8-0x00003700 errors.

2. Local Network Problems

The remaining 70% of 8-0x00003700 instances stem from player-side network problems, such as:

• Faulty internet connections
• Router firmware bugs
• Incorrect port forwarding setups
• Overactive firewalls or antivirus softwares

These local problems prevent game data packets from smoothly transferring between the player‘s device and Ubisoft‘s servers.

The table below shows the most common error codes faced by Rainbow Six Siege players related to connectivity issues:

Impact on Players

The 8-0x00003700 message translates to "The Rainbow Six Siege servers are unreachable, please try again later".

As the error suggests, players facing code 8-0x00003700 can neither access multiplayer matches nor leverage any online features. This persists until connectivity resumes normal function.

Prolonged disconnections risk player progression loss, especially for timed seasonal events. It also prevents squad coordination between friends for group missions.

According to Ubisoft‘s telemetry data, the average Rainbow Six gamer plays 3 hours per session and completes around 5 multiplayer matches hourly. A sudden error 8-0x00003700 disruption costs them almost half a gaming session along with hard-earned progression.

On public multiplayer lobbies, random server errors unfairly count as deliberate match abandons or rage quits. This affects the player‘s credibility score used for matchmaking.

Troubleshooting Tips

Here are 12 potential solutions to resolve Rainbow Six Siege error 8-0x00003700 on your end:

1. Check Server Status

First visit the Ubisoft Server Status page and confirm any ongoing issues. If servers display degraded performance in your region, the connections should automatically restore within 1-2 hours.

2. Restart Hardware

Restarting network equipment like routers, modems and game consoles refreshes all connections. This resolves temporary glitches triggering the error 8-0x00003700 message.

3. Ethernet Over WiFi

For gaming PCs, use a physical ethernet connection instead of WiFi for reliable low-latency connections crucial in competitive online shooters like Rainbow Six Siege. This nearly eliminates transient disconnections.

4. Forward Ports

Ubisoft recommends forwarding UDP ports 3074 & 3075 to your game device‘s local IP address for unblocked inbound game traffic. Follow your router manual‘s port forwarding instructions to set this up.

5. Disable VPNs

Jury-rigged VPN connections often disrupt gameplay traffic. Disable any active VPN softwares while playing Rainbow Six Siege.

6. Pause Anti-virus, Firewalls

Overzealous anti-virus scanners or firewalls occasionally block legitimate game data packets. Whitelist the game executable file and temporarily disable such softwares when facing error 8-0x00003700.

7. Reinstall & Update

Repair missing or corrupt game files by reinstalling Rainbow Six Siege completely. This eliminates any cached bugs. Also install the latest game update patches for compatibility fixes.

8. Flush DNS

Clear your device’s DNS cache and flush DNS via command prompts to erase bad redirects.

9. Renew IP

Force a fresh IP lease from the router’s DHCP pool using MAC address spoofing or the ipconfig /release /renew method.

10. Remove Background Downloads

Pause any bandwidth-intensive desktop clients (Steam, Windows Update etc) temporarily degrading the internet speed.

11. Clone MAC Address

If your router‘s MAC filter blocks new device connections, clone its MAC address onto the game machine‘s network interface.

12. Bridge Connections

As a last resort, bridge local connections over a separate travel router acting as an intermediary to bypass restrictive network policies altogether.

Expert Insights

Gaming industry experts like 302Gaming highlight Rainbow Six Siege‘s "always online" model as a latent single point of failure:

“Persistent connectivity is undoubtedly essential in intensifying the competitive multiplayer experience. But as players increasingly depend on 24×7 access, sporadic server disruptions or downtimes feel far more painful, abrupt and unacceptable, however infrequent."

They further recommend hybrid server redundancy from multiple cloud providers to circumvent reliance upon single vendor platforms:

“Infrastructure diversity and active-active multicloud deployments based on solutions like AWS Outposts must now become the norm for leading titles to deliver baseline availability alongside scalable peak capacity.”

Meanwhile on public forums, Rainbow Six Siege regulars continue rallying for dedicated servers across all regions to maintain consistently low pings and equal standards universally. They frequently criticize Ubisoft for cheaper peer-to-peer hosting optimizing publisher costs over player connections.

Conclusion

In summary, Rainbow Six Siege error 8-0x00003700 represents disrupted communication between players and Ubisoft servers, blocking all online features. While intermittent server issues contribute partially, most cases arise from local network problems incorrectly configured for real-time gaming traffic.
