I have been using the small leather panel before, but after upgrading to 8.1.1.3, the system developed before also had problems, and the new laravel also reported the same error.

Mysql: 5.7.26

PHP: 5.2.17nts and 7.3.4nts

Database operation reported:

Illuminate \ Database \ QueryException (2054 )

SQLSTATE[HY000] [2054] Connecting to 3.22, 3.23 & 4.0 servers is not supported

PDO::__construct(): Connecting to 3.22, 3.23 & 4.0 is not supported. Server is 4.0.27-nt

How to solve this?
