What Is the Perplexity AI Check Your Connection Error?
The “Check your connection” error on Perplexity AI is one of the most frustrating messages users encounter. It usually appears just after you open the app or submit a prompt. Instead of receiving an insightful response, you’re greeted with a message that suggests your internet connection is broken—even when everything else online is working just fine.
This error often tricks users into thinking the problem lies with their network, when in reality, the root cause can come from browser settings, VPNs, firewall restrictions, DNS errors, or temporary platform-side outages. Fortunately, this issue is both common and solvable with a few targeted adjustments.

Sometimes, it’s a sign that something else in your system is misconfigured. - 🌐 Misleads Users When Internet Is Actually Fine
Your connection may be strong—but internal routing issues still trigger the error.
Let’s get to the bottom of it and solve it step by step.
