Why Is Snapchat Not Working? Common Causes of Connection Errors
Outdated Apps and OS Versions
Older versions of Snapchat or your phone’s operating system may have compatibility issues causing the app to crash, lag, or fail to load properly. An outdated Snapchat app often results in Snapchat not connecting or login errors.

Your device’s date and time settings may be incorrect. Snapchat uses these settings to verify your device’s identity with its servers. If your phone shows the wrong time or time zone, it might cause Snapchat login problems or Snapchat internet error messages.
Network Instability
Network instability is one of the biggest culprits. Whether you are on Wi-Fi or mobile data, if your connection is slow or unstable, Snapchat might fail to load stories or send snaps, often showing errors like Snapchat keeps saying “check your connection”.
Interference from VPNs, Ad Blockers, and Router Filters
Ad blockers, VPNs, or router-level content filters can interfere with Snapchat’s communication. For example, some routers or mobile carriers have filters like Web Guard that block Snapchat traffic, leading to connection errors.
Server-Side Issues
Snapchat server issues also happen, especially during app updates or maintenance. In such cases, you might see Snapchat server down or the app failing to connect for many users worldwide.
