Dear aspirant,

If you’re unable to log in with your registration ID, there could be a few common issues. Double check that you're entering the correct ID without any mistakes. Make sure the password is also correct. Sometimes, the portal may be temporarily down or under maintenance so that could be one reason. You can check after a few hours. Also, make sure that you're on the correct official website or portal. If the issue still continues, it's best to contact the official support or helpline of the concerned authority.

Thanks
