Internet exporer error while Executiong SOLMAN_SETUP transaction

HI Experts,

I am facing an issue while executing the transaction SOLMAN_SETUP.

I login to the SOLMAN using solman_admin, but when i execute solman_setup an IE page appears saying "Internet explorer cannot display the webpage"

The address that it is taking is as below which i think is missing the hostname. The parameters are correct.

One more thing we used to use this transaction before in the same system but when we are trying now we are getting this error.

Please help.

Thanks!!!
