I am trying to log in to the sandbox: https://fmcrestapisandbox.cisco.com/ui/login. I have reserved the sandbox and received the username/password. however, my authentication is not working. I have tried multiple attempts on multiple browsers. Please assist. 

Thanks,

Hi, 

Apologies but we had a problem with that sandbox. I have made some changes (including an upgrade). Its working now. Can you try again? 
Thanks,

Thanks, jokearns1, authentication is working. 

I see a certificate error, but all good after I bypass the cert check on my browser.
