I implemented login system using UserPrincipal in Tomcat. When I press wrong credentials, it correctly redirects to an error page. The problem is with correct data. Every time when I log in using correct data, I am redirected to HTTP Status 408 - Request Timeout. Terminal doesn't show any logs. None of StackOverflow solutions worked for me. What may be the reason?I completely don't know what to do. Please help me, I put a lot of effort into it and I would like to continue my work! Did I forget about something?
