Springboot Error: There was an unexpected error (type = internal server error, status = 500)

There was an unexpected error (type=Internal Server Error, status=500).
This error was found in running springboot.

There was an unexpected error (type=Internal Server Error, status=500).
Authentication failed for token submission [org.apache.shiro.authc. UsernamePasswordToken – null, rememberMe=false]. Possible unexpected error?(Typical or expected login exceptions should extend from AuthenticationException).
I had to rewrite it and found out that it was caused by Maven and the Thymeleaf dependency was added incorrectly.
Maybe I wrote it and @{} didn’t work correctly, so I took one from the internet and got the wrong one.
The original dependency was this

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>

I ended up with this

<!-- https://mvnrepository.com/artifact/org.thymeleaf/thymeleaf -->
<dependency>
    <groupId>org.thymeleaf</groupId>
    <artifactId>thymeleaf</artifactId>
    <version>3.0.12.RELEASE</version>

Git Pull Error: RPC failed; curl 56 OpenSSL SSL_read: SSL_ERROR_SYSCALL, errfno 10054

The following error occurs when git pull

error: RPC failed; curl 56 OpenSSL SSL_read: SSL_ERROR_SYSCALL, errfno 10054
fatal: The remote end hung up unexpectedly
fatal: early EOF
fatal: unpack-objects failed

Execute the pull command again after the following Settings

git config http.postBuffer 524288000

This command sets the size of the communication cache. The previous error was caused by too much synchronized data.
The config parameters here can be seen in the config file in the file directory
