Can't login from other pc

Hi all

I got a question,
I installed Asterisk on one Linux, and I can login into Asterisk_GUI from this linux machine,
but I can’t login into GUI from my other PC(windows).
It show the login panel in windows, so the connection and firewall are not the problem.
but when I entry ID and password, it show Invalid PW and ID.

did anyone also have the same question?

Thanks
Gerald.

Do you use the manager to authenticate? If you only permit the 127.0.0.1 maybe its the cause.
