It was ok Before, but I don't know why the site could not access today. browser throw 302 excception.
302 basically means it should redirect to other page but the page is not available . Are you using custom authentication or have implemented SSO for redirection of this url to some other url ?
Thanks,I don't use SSO,I use the system's own authentication.It's ok before.I do not know if the configuration of the server was modified
Can you please attach Application logs for this ?
