SQL ERROR

I have a fairly low traffic server on Digital Ocean setup via Forge running Laravel v5.1. For the database it connects to a AWS -> RDS Amazon Aurora (mysql) instance. I have been seeing this error come up many times and I'm not exactly sure the best approach on how to address / fix it. Any ideas or suggestions would be welcome. Thanks!
