Question regarding my app

Hello, I am not a tech founder, but had a delivery app built for iOS and Android with a web based admin panel. What has happened is that I am no longer able to access my admin panels the address is adminpanel.urbangoodzdelivery.com/admin and also I have noticed that none of the vendors show up on the app itself anymore. At first I thought it was a domain issue, but was told it is fine. My next guess is there is something wrong with Twilio but I wouldn't think that Twilio would essentially have my entire app down. My last guess is it may be an AWS problem. Has anyone had this issue or would should I do?
