My Laravel 5.7 website has been experiencing a few problems

Answer 1

If you see this message randomly, possible reasons:

1. Your MySQL is behind a proxy, and they are using different timeout config.

2. You are using PHP's persist connection.

You may try to dig into the problem by these steps:

1. Make sure your connections to MySQL have long enough timeout (eg: proxy setting, MySQL's wait_timeout / interactive_timeout)

2. Disable the persist connection at PHP side.

3. Do some tcpdump if you can to see what happend when you got the error message.
