Quick checks, in order
Test the same page in another browser
Confirm that the internet connection and website are working.
Open an Incognito window
If it works, extensions or stored site data are likely involved.
Disable network-related extensions
Test privacy, VPN, proxy, ad-blocking, and security extensions one at a time.
Review Chrome proxy and secure DNS settings
Return custom settings to automatic only if you can restore them.
What works outside Chrome?
Focus on Chrome extensions, profile, proxy, secure DNS, and security filtering.
Treat it as a wider network, DNS, router, or provider problem.
An extension, cookie, or cached site state is likely.

Frequently asked questions
Should I reinstall Chrome first?
No. Incognito, extensions, proxy, secure DNS, and a new profile are more targeted tests.
Why can apps work when Chrome cannot?
Apps may use different DNS, proxy, certificate, or network paths than Chrome.
