Issue with demo

Maybe this is the problem? Did you try and serve the canister from 127.0.0.1 and access it locally?

How to run canister on public network?

I think the issue is because 192.168.1.9 is not considered as a secure context and so your browser doesn’t load the SubtleCrypto API ( https://developer.mozilla.org/en-US/docs/Web/API/SubtleCrypto ), while http://localhost (or 127.0.0.1) is considered as secure. try typing isSecureContext in the webconsole, if it returns false it means that you need to serve this endpoint via SSL

Another thing you could try is to empty your browser cache.
