What version of osTicket are you running?
Can you try a different browser? It seems Java is disabled in your Chrome browser. I honestly have never seen this error before.
Cheers.
willielm That looks like the admin interface from an old HP Procurve switch. Are you sure you've got the right IP address for your server running osTicket??
Check the logo at the top left of the page... if it looks like this, you're connected to a switch 😉
