Common Causes
- Unstable Internet Connection: A fluctuating or weak internet connection is a common culprit, leading to dropped packets and a broken connection with Discord's servers.
- Firewall or Antivirus Interference: Your firewall or antivirus software might be mistakenly blocking Discord's connection, especially if it's a newly installed program or if Discord was recently updated.
- Discord Server Issues: Although less frequent, problems on Discord's end, such as server outages or maintenance, can trigger connection errors.
- Outdated Discord Application: Using an outdated version of the Discord application can cause compatibility issues and connection problems.
- Conflicting Applications: Certain applications running in the background may interfere with Discord's network connection.

Method 4: Update Discord
Step 1: Close Discord completely. Make sure it's not running in the system tray.
