same here just few hours ago, but i can't even open any manga website (but i can load bato.to just the image doesn't appear) have an error saying ERR_QUIC_PROTOCOL_ERROR. so i just search the solution
1.Open Google Chrome.
2.In the address bar of the new tab window, type chrome://flags/ and press Enter.
3.Don’t get dismayed at a warning message that says 4.Careful, these experiment may bite. Once you see it, click Ctrl + F simultaneously to open search box.
5.Type Experimental QUIC protocol in it and select Disable from the drop down menu.
6.Finally, relaunch(likely it will appear and recommend itself to do this) Google Chrome.

FEELS LIKE HACKERMAN! (even though i just search for the solution)
