I am using the ReallySimpleJWT Library and I have changed the server and reinstalled the libraries with Composer again. Only this library gave an error and I don't understand why.

What could be the problem?

Line 23:

$result = Token::validateExpiration($token, $secretForToken);

What could be the cause of this error?

The static method your are trying to access on the Token class does not exist.
