Your problem may be caused by the design. For example:
The user visits your website, and you redirect directly to cas
cas returned something, in short it is an incorrect result (maybe caused by your program, or it may be a problem with cas itself)
Your verification failed, it was determined that the user was not logged in, and then it was redirected directly to cas.
The result is that you keep jumping and can’t get out.
If this is the problem, then the solution is: don’t jump directly without user operation. Change it to this:
When a user visits your website, a link appears on your website, such as "Log in from cas", and the user clicks this link
Slightly
Your verification failed and the error page is returned but does not jump
