Recently I had been facing problem loading Google sites such as its search engine, Gmail, Youtube, etc.
It is either take extra ordinary long time to load, or just failed with `ERR_QUIC_PROTOCOL_ERROR`.
I did a search and found I am not alone, and below are the solution :
- Open a new tab in Chrome, and type `chrome://flags/` into address bar, then press Enter.
- Search for `Experimental QUIC protocol`
- Disable it.
- Restart Chrome. Done.
It had been about a week, and the error never happen again.
