Hi! I’m Henry Adams, here to help you get your GROWLR app back up and running. So you’re facing two issues: the app won’t connect to the network, and now it won’t open at all on your Windows device using the WebKit browser, right?

To get a clearer picture, could you tell me a bit more:
- Did the app stop connecting after an update or a device change?
- Have you tried restarting your computer or closing and reopening the app?
- Are other apps or websites working fine with your current internet connection?

Meanwhile, let me walk you through some quick fixes that often work for GROWLR app network and startup problems.

### Step 1: Clear the app cache and data
Since you’re on Windows using WebKit as your browser engine, clear any cached data or cookies related to GROWLR from the browser settings. This helps remove corrupted data that might prevent the app from opening or connecting.

### Step 2: Check network settings
Make sure your internet connection is stable. Try switching between Wi-Fi and Ethernet or even a mobile hotspot if possible. Sometimes GROWLR might have trouble connecting on certain networks or under firewall restrictions.

### Step 3: Update app and Windows system
If you use a desktop app or a web app, ensure that your GROWLR app version and Windows 10 are fully updated. Updates often fix bugs causing crashes or connection errors.

### Step 4: Restart your device
A simple restart can resolve many software glitches affecting network connections or app launches.

If none of these steps work, you might want to uninstall and reinstall the app. For web app users, clearing cache plus ensuring your browser is up to date usually helps.

If you’ve tried these already, please let me know which ones so I can suggest some deeper troubleshooting, like checking firewall exceptions or network proxies.

Also, if you want, I can check for any recent server outages or known issues affecting GROWLR.

Are you okay trying those steps? Let me know how it goes!
