CodePudding user response：

After communicating with a friend After searching a lot, I found the cause of the problem is the server itself iis As it gives a default value for the maximum upload limit of 2 megabytes

Solve the problem if the server is on iis

IIS -> web. config :

<?xml version="1.0" encoding="utf-8"?>
