Those are normal. .But you are looking at the wrong side for troubleshooting. FOP2 has several components, the server that talks to the asterisk manager, and web clients that talk to fop2 server.
As far as I understand, your problem is with the client, even more so, I would say with the web server setup, as you do not even see a login page. So, you should stop looking at the fop2 server, and you should start looking at your web server setup/logs.
