We've recently purchased a new Juniper SA2500 for our client. I've initially configured the device so I can do a burn-in test and check for licenses, etc. When I was able to configure the IP of the box, I logged inside via web. It successfully logged in. Then I tried disconnecting the UTP cable so I can connect my LAN to the internet. After that, I connected my LAN port again to the SA2500. This time when I tried to log via web, it only shows Invalid username or password. Please re-enter your user information. I didn't change anything in the box and I even created a new user so I can log with a different user. Unfortunately, the same thing happens.
For those who know how to solve this case, please help me..
When you say "I logged inside via web" I guess you are referring to logging into SA as an admin and that you could after disconnecting the cable.
Even after you created another admin account you still could not login?
Can you try to create a super admin session (option 6 on admin console) and then login, there after check user access / admin logs to see if any errors.
