Hi there! I see you're encountering 404 and 406 errors with Mike's Weather Page app. Just so I understand better, are these errors happening when you try to access the website through your Mac running OS X 10.15.7? Also, do the errors appear consistently on specific pages or randomly? Any additional details you can share will help me guide you better.

Meanwhile, here’s a general approach to address these errors:

### For 404 (Page Not Found) Error:
1. Check the URL: Sometimes, a typo or outdated bookmark can lead to a 404 error.
2. Clear browser cache: On macOS, you can do this in Safari or whichever browser you use by accessing the Preferences > Privacy > Manage Website Data, then remove data for the site.
3. Try a different browser or device: This can help isolate if the issue is local.
4. Check for app or site outages: Mike’s Weather Page recently experienced a traffic influx causing temporary downtime; the site might still be stabilizing 1.

### For 406 (Not Acceptable) Error:
1. Clear browser cache and cookies: Sometimes outdated cookies cause content negotiation issues.
2. Disable any browser extensions: Some plugins modify headers that cause the server to reject the request.
3. Try accessing the site with a different browser or in private/incognito mode.
4. If you’re comfortable, check your browser’s request headers to ensure it accepts common content types.
5. The 406 error means the server cannot provide a response matching your browser’s ‘Accept’ header 2.

Given the recent traffic issues Mike’s Weather Page had, server-side instabilities might be causing these errors too. If you have tried the basics like refreshing, clearing cache, and trying other browsers or devices, please let me know, and we can look into more specific troubleshooting.

Are you seeing these errors only with Mike’s Weather Page app or other sites too? And could you share which browser you’re using? This info will help me tailor the guidance further.
