I am following the tutorial Use the Sudo Pallet ....Built & run the upgraded runtime - cargo +nightly-2020-10-06 run --release -- --dev --tmp.... Connected to Polkadot JS Apps - https://polkadot.js.org/apps/#/extrinsics?rpc=ws://127.0.0.1:9944.

I am now receiving an error (initializing connection - waiting to make a connection) - and page does not load correctly.

enter image description here

I receive the same issue when I open Canvas-UI - e.g. if I select local node receive error You are not connected to a node Ensure that your node is running and that your Websocket endpoint is reachable....

Whereas when I select 'canvas test' I can connect!

Have recently upgraded FRAME runtime sudo pallet - RuntimeVersion struct from spec_version: 1 to spec_version: 2.

Could this be a cause?

  • This is likely a browser related issue. Although as you point out, you for sure want to use the same spec version in all applications. This _should_ be picked up by the API though. It will display this information on the template and on https://polkadot.js.org/apps/ --- Check your browser settings. – Nuke Apr 08 '21 at 22:40

what I did to solve that was installing Polkadot.js extension, and on settings (right left corner), select polkadot and the first option. Then press switch, and its running.

Please ensure you are not using Firefox Browser for the polkadot UI. That is the time I have add a similar error. Use Google Chrome Browser instead.
