mysql - SQLSTATE[HY000]: General error: 1835 Malformed communication packet on LARAVEL

Question

Suddenly got

SQLSTATE[HY000]: General error: 1835 Malformed communication packet (SQL: select * from tb_users where (username = 121211) limit 1)

on Laravel.

I already checked this: MySQL: ERROR 2027 (HY000): Malformed packet, but it seems a different case.

1. I've successfully logged in to MySQL after previously login using SSH (using: mysql -u -p).
2. I've successfully logged in to MySQL directly from a remote PC (using: mysql -h [IP] -u -p).

But my Laravel got the error I mentioned before. Any experience in this?

Answer 1

All my Laravel apps running PHP 7.2 had this error but those running on PHP 7.3 did not. So I changed the PHP version to 7.3 and the problem was fixed. (Running Laravel 7)
