[Bug]: Infinite local network connection after its shutdown

[daoio]

Describe the bug

I've booted local node using Hardhat and created public endpoint (with just http://127.0.0.1:number_of_port all works properly from beginning to the end) to node's HTTP server. Then I've added local network to Metamask extension adding that endpoint in RPC URL, all was working fine, but after shutting down network, Metamask now stuck with "Connecting to hardhat (that was network name)" title, even after pc reboot it still shows an infinite (actually an hour has passed but it still stuck in it) connection and no buttons work.

Steps to reproduce

1. npm init
2. npm install hardhat --save-dev
3. Install hardhat dependencies
4. npx hardhat node
5. Create public endpoint to logged http url
6. Add network to Metamask extension with that public endpoint as RPC URL
7. Shutdown node
8. Open Metamask extension (here infinite connection should appear)
9. Try to close browser and reboot computer
