Trying to use MetaMask. Says it is connected but is not connected

I am trying to log into TagProtocol with Metamask through the Binance Smart Chain.
Metamask says I am connected.
However, when trying to connect the 2, it says : Error
No Ethereum provider was found on window.ethereum.

This is on my desktop, laptop, and tablet.
I do not have or want a cell phone.

Support through Metamask has not responded.
The connect button is green and says it is connected on the Extension.

Try this:

Just uninstall any extension you’re not using… It could be interfering with metamask and that’s why it wouldn’t let us connect to web3. Now you can try again
