When Claude access isn't working, one of the most useful early diagnostic steps is simply figuring out whether the problem is following your network or following your account — a distinction that changes everything about how to fix it.
The cross-check method
- Try a different network with the same account. If the problem persists on an entirely different network (like switching from home Wi-Fi to mobile data), that points away from a network-specific cause and toward something account-, browser-, or service-related.
- Try a different device on the same network. If a different device works fine on the same network, that points toward something specific to the original device (browser, cached data, local settings) rather than the network itself.
- Try a different account on the same network (if available). If a different account works fine from the same network, that strongly suggests the issue is specific to the original account rather than the network.
Reading the results
- Fails everywhere, same account: likely account-related — check billing, organization settings, or contact official support.
- Works elsewhere, fails only on one network: likely network-related — see Why Claude May Not Be Available on Your Connection for network-specific troubleshooting.
- Fails only on one specific device: likely browser or local-configuration related — try clearing browser data or testing in a private window.
Using the checker as part of this process
NetRiskScan's Claude Access Checker is most useful specifically for the "is it my network" branch of this diagnosis — run it on each network you're testing to compare results directly.
FAQ
What if I don't have access to multiple devices or networks to test?
Even a single alternate data point (trying mobile data instead of Wi-Fi, for instance) meaningfully narrows down the likely cause compared to no cross-check at all.
