foundry vtt your connection appears to be closed

Foundry Virtual Tabletop (FoundryVTT) is a powerful tool for running tabletop RPGs online, but sometimes you encounter frustrating connection issues. One common problem is the dreaded "Your Connection Appears to be Closed" error message. This article will guide you through troubleshooting this issue, helping you get back to your game quickly.

Understanding the Problem

The "Your Connection Appears to be Closed" error in FoundryVTT typically indicates a problem with the communication between your computer and the FoundryVTT server. This isn't always a problem with your internet connection itself; it can stem from several different sources. Let's explore the most common causes and solutions.

1. Network Issues: The Obvious Culprit

Internet Connectivity: The most basic check is your internet connection. Is your internet working properly? Can you browse other websites? If not, troubleshoot your internet connection directly before proceeding with FoundryVTT-specific solutions.
Firewall/Antivirus: Firewalls and antivirus software sometimes block FoundryVTT's communication. Temporarily disabling these (only for testing purposes!) can help determine if they are the cause. Remember to re-enable them afterward.
Router Problems: A malfunctioning router or a congested network can interrupt the connection. Try restarting your router. If you're on a shared network, see if other devices are experiencing connectivity issues.
DNS Issues: Occasionally, DNS (Domain Name System) problems can interfere. Try flushing your DNS cache (instructions vary depending on your operating system, a quick online search will provide guidance).

2. Browser-Specific Problems

FoundryVTT runs in a web browser, so browser-related issues are common.

Browser Extensions: Browser extensions, especially those related to security or ad-blocking, can interfere. Try disabling extensions temporarily to see if one is causing the problem.
Outdated Browser: An outdated browser might lack the necessary features or security protocols for a stable connection. Update your browser to the latest version. Supported browsers include Chrome, Firefox, and Edge.
Browser Cache and Cookies: Clearing your browser's cache and cookies can resolve conflicts. This is a good general troubleshooting step for many web applications.

3. FoundryVTT Server Issues

The problem might not be on your end at all.

Server Downtime: Is the FoundryVTT server you're connecting to experiencing downtime? Check the server's status page or community forums for any reports of outages.
Server Overload: A heavily loaded server might struggle to maintain all connections. Try connecting at a less busy time.

4. Client-Side Problems

Let's examine potential issues on your computer running FoundryVTT.

Outdated FoundryVTT: Make sure you're running the latest version of FoundryVTT. Updates often include bug fixes that address connection issues. Visit the official FoundryVTT website for updates.
Corrupted Game Data: Corrupted game data can sometimes disrupt connections. Try creating a new game to test if the problem persists. If the new game works fine, your original game data might be corrupt and need to be repaired or replaced.
Insufficient Resources: FoundryVTT can be resource-intensive, especially with large modules or many players. Ensure your computer has sufficient RAM and processing power. Closing unnecessary applications can also free up resources.

Troubleshooting Steps: A Summary

Check your internet connection: The most fundamental step.
Restart your router and computer: A simple reboot can often resolve temporary glitches.
Disable firewall/antivirus (temporarily): To rule out software interference.
Update your browser and FoundryVTT: Ensure you're using the latest versions.
Clear your browser's cache and cookies: Remove any conflicting data.
Disable browser extensions (temporarily): See if an extension is causing problems.
Check the FoundryVTT server status: Rule out server-side issues.
Create a new game: To test if game data is corrupted.
Monitor your computer's resources: Ensure sufficient RAM and processing power.

By systematically working through these steps, you should be able to pinpoint the cause of the "Your Connection Appears to be Closed" error and get back to your FoundryVTT game. Remember to re-enable firewalls and antivirus software after testing. If the problem persists, seeking help from the FoundryVTT community forums is a good next step.
