Hi Linda,
Thanks for reaching out and letting me know what you are experiencing. I understand how confusing it can be when your browser suddenly refuses to load a site and shows an unexpected error. It can be especially frustrating when you need to access something important and the page simply will not refresh no matter what you try.
The message saying that learn.microsoft.com sent an invalid response usually means something is interrupting the connection or causing Chrome to process the website incorrectly. Along with the usual troubleshooting steps another helpful approach is to restart your device to clear any temporary issues that may be affecting the browser. After restarting you can reset Chrome’s network settings so it rebuilds a fresh connection. It may also help to temporarily turn off your antivirus or firewall to see if they are blocking the site in the background. If the problem only happens on secure websites checking that your device’s date and time are correct can resolve certificate‑related errors. You can also try connecting through a different network such as a mobile hotspot to determine whether the issue is tied to your current internet connection.
When you try these additional steps do you notice if the problem happens only with learn.microsoft.com or with other secure sites as well?
I hope this answer is helpful if you have further questions feel free to reply back
Regards,
Marcelo
