Troubleshooting

Local domains are slow or not working

When your local domains have a slow response time or don't work at all, this may indicate issues with the mDNS protocol, browser DNS cache, system DNS cache, or system permissions.

To resolve it, try the following:

• Check LocalCan's network permissions

  1. Open macOS System Settings
  2. Go to Privacy & Security
  3. Scroll down to Local Network
  4. Make sure LocalCan has permission (toggle switch is turned on)

• Check if the issue is browser-specific

  Test your local domain in different browsers (Chrome, Firefox, Safari) to determine if the slowdown only happens on a specific browser. If so, clear the browser's DNS cache.

• Clear browser's DNS cache

  Example for Chrome:

  1. Navigate to chrome://net-internals/#dns
  2. Click Clear host cache
  3. Navigate to chrome://net-internals/#sockets
  4. Click Close idle sockets, and then click Flush socket pools.

• Clear system DNS cache

  Run these commands in terminal to clear the system DNS cache and restart mDNSResponder:

  sudo dscacheutil -flushcache
  sudo killall -HUP mDNSResponder
  sudo killall mDNSResponderHelper
  

• Restart LocalCan

• Restart WiFi (turn off and on)

• Restart your router

• Switch to different WiFi network

Most domain issues can be resolved by checking permissions, clearing DNS caches, and restarting network services. If the problem continues, it might indicate a deeper network configuration issue that requires additional investigation.
