Google有时可以访问，有时不能，求大神指点。

System environment: Ubuntu16.04 Shadowsocks-Qt: `Version 3.0.1` Chrome: `78.0.3904.108（正式版本） （64 位）` The test delay has been stable at around 150ms, but the browser often cannot access Google for no reason (at this time, the test connection delay is also normal and there is no timeout). But after a while, everything is fine. Have you encountered the same problem?
