SSC — having problem logging in at ssc website

Dear sir/madam,
Ssc stenographer online form 2018 has been published by ssc. I went on the website and log in and it asked for user id and password. I entered the details and it showed wrong user id and password. I thought there should be any mistake... I recovered the password and again logged in but it is again showing invalid username/password... Repetitively... I tried from many browsers but results same... Please do the needful because its not only my problem but thousands student's problem...
