Can't log into ambari web UI using username and password

[#1]

After I can't get ambari password setted, this time I faced another issue with ambari login.

I download the newest harton sandbox for virtualbox. After I import sandbox into virtualbox. The network setting is NAT. As I set the password for the ambari server, the shell showed that 'Ambari Server 'start' completed successfully', and the postmaster, ambari-server is running, but I got problem when logging into ambari web UI (127.0.0.1:8080), the browser provide with the login interface requires you to input username (admin) and password(I set myself), but after input this information, the ambari UI will not show, instead, the login interface will show again without showing any error message or successful message, seems like I have input nothing. What may cause this problem? And how can I solve it? thanks!

What command you use for password reset ? was it "ambari-admin-password-reset" ?

Please try clearing the cache and retry.

Check if you see any error in /var/log/ambari-server/ambari-server.logs

This is what I got in log, don't find the problem reason. Also, how can I clean the cache in sandbox, I am new to centOS

Yes, I think this is not relate to password change, before I changed password, I could also not login using admin/admin

The problem solved, this is because some application(oracle) is taking the port 8080, and the ambari is unable to use the port 8080, the login screenshot I upload is just the login for the oracle application, I changed the host port from 8080 to some else that no application is using (like 8083), so that everything is OK, it is really a silly mistake.
