Robtex.com is not working

In my situation the ‘www.robtex.com’ cannot be used to search for the information about the target web application… I already logged in with my gmail account with still not working for me… is there anything to do to fix this? Thank you!

Never heard of this tool. Also, Robtex only performs reverse DNS lookup and whois. You can easily find these things by just googling - reverse DNS check or whois info. You don’t need any tool for that
