I am using paid Wowza license ($65/month). It was working fine, but stopped working all of a sudden yesterday.

I am currently using 02 servers, on the first server, it wont let me log in, even though I’m passing right username/password,

and on the other server, I am getting: ‘The license key you entered is not valid’. I set the right key manually, and it still wont work. I crossed checked server license key file, and that has the right key stored as well.

I also crossed checked, all payments for previous month have already been paid.

Why is this happening?
