If you’re an avid Magic: The Gathering Arena player, chances are good that you rely on companion tools to track your decks, performance, and match history. One of the most popular among them is MTG Arena Tracker. However, like all software, it’s not immune to connection issues. If you’re staring at a stubborn “connecting” message or incomplete data, this guide will help you diagnose and fix the problem quickly.
TL;DR
MTG Arena Tracker not connecting? First, make sure MTG Arena is running and the log file is being generated. Check firewall/antivirus settings and ensure you’re running the latest version of both the tracker and the game. If issues persist, reinstall the tracker or reset your settings. This guide walks you through each step to get you back on track.
Why MTG Arena Tracker Might Not Connect
MTG Arena Tracker works by reading logs generated by MTG Arena itself. If the tracker can’t find those logs or access the internet, it will fail to connect. Understanding the root cause is the key to a quick resolution.
Common Causes:
- MTG Arena is not running or hasn’t been started yet
- Log files are missing or not configured properly
- Antivirus/firewall software is blocking the tracker
- Corrupted or outdated tracker/client files
- Server outages or backend issues
Step-By-Step Fix Guide
1. Confirm That MTG Arena Is Running
MTG Arena Tracker requires the game client to be running. If MTG Arena is closed, the tracker won’t find logs to process.
- Launch MTG Arena first
- Then open MTG Arena Tracker
Sometimes starting the tracker before the game can cause initialization problems, so the order matters.
2. Check Log File Generation
MTG Arena Tracker reads from a log file located on your system. If this file isn’t being created, the tracker won’t receive any data.
Locate the log file here:
C:\Users\[YourUsername]\AppData\LocalLow\Wizards Of The Coast\MTGA\output_log.txt
If the output_log.txt file isn’t showing recent updates or doesn’t exist, you may need to:
- Re-enable log creation in MTGA settings (if applicable)
- Reinstall MTGA to restore default logging behavior
3. Make Sure Tracker Has Internet Access
Outdated Windows Firewall rules or a too-strict antivirus could prevent MTG Arena Tracker from connecting to its servers.
To fix this:
- Whitelist MTG Arena Tracker in your firewall and anti-virus
- Check that your network connection is stable
- Try running the application as an administrator
Most programs will need to communicate with their own servers to function properly. While you’re at it, ensure your network isn’t blocking the tracker tool entirely, especially if you’re behind a company VPN or proxy firewall.
4. Update Everything
Running outdated versions of either MTG Arena or the tracker tool can cause compatibility issues that prevent connection.
- Download and install the latest version of MTG Arena Tracker from the official website
- Update MTG Arena client via the launcher
Sometimes a patch changes the log structure, which can break compatibility until both ends support the new format.
5. Identify Server-Side Downtime
Another common reason the tracker won’t connect is that its own backend services are down. Visit the official Discord or website status page to see if there’s a known outage.
Try checking these:
- MTGA Tracker Status Page
- MTGA subreddit or official Discord server for notices
If everything else looks okay and others are reporting issues, it may be a temporary service outage.

6. Reinstall the Tracker
If none of the above steps work, you might be dealing with corrupted files or settings. Doing a clean reinstallation can resolve such problems.
Here’s how to do it safely:
- Uninstall the app via Control Panel or Windows Settings
- Delete the configuration folders located in:
C:\Users\[YourName]\AppData\Local\MTGATracker
- Re-download and install the latest version from the official website
Once reinstalled, start MTG Arena first, then launch the tracker tool.
7. Reset Settings to Default
Sometimes changes to settings like window configuration or log file paths can impact functionality. A reset can eliminate that variable.
To reset settings:
- Find the configuration file (e.g., settings.json)
- Delete or rename it and restart the tracker
This forces the app to generate a fresh configuration on next startup.
Advanced Troubleshooting
Review the Tracker’s Log
MTG Arena Tracker itself generates logs. Open the application folder and look for log files (e.g., tracker.log or error.log).
Reading through these logs can give clues as to what’s going wrong. Look for near-term timestamps and phrases like “failed to connect,” “log file access denied,” or “server unreachable.”
Contact Support or Use Community Forums
If you’re still stuck after all of the above steps, reach out to the developers or post a question in the community:
- MTGA Tracker Official Discord
- Open an issue on the appropriate GitHub repository or Form
- Ask for help on MTG Reddit or community forums
Preventing Future Connection Issues
Now that your tracker is running again, follow these best practices to avoid future problems:
- Keep both MTG Arena and the tracker regularly updated
- Avoid switching log file directories or access permissions
- Disable third-party “game booster” or optimization tools that might interfere
- Join MTG Tracker’s Discord to get notified about known issues or updates
Final Thoughts
MTG Arena Tracker is an incredibly useful tool, but like all companion apps, it depends on a delicate connection to both your local files and external servers. When it refuses to connect, it’s usually due to log file issues, software conflicts, or network access restrictions. By following the steps above, you can identify the exact issue, address it efficiently, and return to the game with your tracker fully operational.
Don’t wait for a fix to fall into your lap—take action now and get your gameplay stats back on screen where they belong.
