If Snapchat doing not open for you, you need to check if it’s down for everyone or not. There are two places to check whether the Snapchat server is down. Down Detector is a site that provides you with the status of various websites and their services. If your Snapchat is not working or showing any issue go to Down Detector and check whether Snapchat is having problems or not. OR visit the @snapchatsupport Twitter page. If Snapchat has any issue or maintenance work, then Snapchat will have tweeted about it.
