# How to resolve connection failure error?

If your system check shows a **“Connectivity: Failed”** status, your device is unable to reach Talview’s servers. In this article, we’ll guide you through common causes and solutions to resolve connectivity issues and ensure a smooth session.

## ✅ Common Causes and Fixes

| **What Might Be Wrong** | **What You Can Do** |
| :- | :- |
| Your internet is slow or unstable | Restart your modem/router. If possible, switch to a wired (LAN) connection. |
| Weak Wi-Fi signal | Move closer to your router or change to a stronger network. |
| VPN or proxy is interfering | Disable VPN/Proxy and try again. |
| Using a school or office network | Contact your IT team to **whitelist Talview domains or use a personal hotspot.** |
| Multiple background apps | Close apps like video streaming, cloud backups, or downloads. |
| Your browser is outdated | Update to the latest version of Google Chrome, Microsoft Edge, Safari or Firefox |
| Security software is blocking access | Temporarily disable or allow Talview through your firewall/antivirus. Ask IT for help if needed. |
| You see “Talview\.app refused to connect” | Your browser, network, or security software is blocking the diagnostic tool from loading. Disable browser extensions such as ad blockers, and turn off any VPN or proxy. If you are on a school or office network, ask your IT team to allow access to Talview domains, or switch to a personal hotspot. Then refresh the page, or try a different browser. |
