Hi there! I see you're running into a 502 Bad Gateway error while trying to use the Solar System Scope app. Let's work together to get this sorted out.

Just to clarify, are you encountering this error when launching the app, or when trying to access a specific feature or webpage within the app? Also, are you using the web app or a desktop/mobile version?

Meanwhile, here’s a general approach to fix a 502 Bad Gateway error specifically for your Windows device using WebKit:

1. Reload the Page/App
Sometimes the error is temporary. Try refreshing the page or restarting the app.

2. Clear Browser Cache
Since you are on WebKit (likely using Safari or a browser based on WebKit engine), clear the cache and cookies which can help remove corrupted data.

3. Try Incognito/Private Mode or Another Browser
This will help rule out browser extensions or cached data interfering.

4. Check Your Internet Connection
Make sure your network is stable and not blocking any services that Solar System Scope uses.

5. Restart Your Device
A simple reboot can resolve temporary network or system glitches.

If none of these steps help, it's likely a server-side issue (on Solar System Scope's end). In that case, waiting and checking their official status page or social media for outages is recommended.

Can you please let me know what you’ve tried so far and any details about when exactly the error pops up? That way, I can tailor the next steps for you.
