HTTPError: HTTP Error 503: Service Unavailable

Answer 1

Does this by any chance happen only with Chrome? I ran into a similar issue that produces the exact same stack trace (albeit with a 407 instead of a 503), so I'm curious to see if the same solution would help here.

Navigate to Control Panel > Internet Options > Connections tab > LAN settings > Advanced. Then, insert 127.0.0.1 into the Exceptions box. In my case, this was sufficient to prevent the crash upon calling .quit().

Answer 2

This is an issue on Chrome browser. The following steps will give you the fix.

1| Uncheck the Check Box, By Proxy server for local address

2| Click on Advanced Tab

3| Enter 127.0.0.1 under Exceptions panel

4| Click ok
