Troubleshooting Connection Issues

Last updated:

If Obscura struggles to connect or a website blocks you, the settings below can help.

Enable TCP/TLS Tunnelling

Section titled “Enable TCP/TLS Tunnelling”

If Obscura has worked before, and you’re on a new network or one with strict firewall settings, the network may be blocking UDP traffic. Obscura’s tunnel uses QUIC (which is UDP-based) by default. Switching to a TCP/TLS tunnel routes the tunnel over TCP instead, which most networks allow.

  1. Open the Obscura app

  2. Navigate to the Settings tab

  3. Open Experimental

  4. Enable Use TCP/TLS tunnel

Rotate Your WireGuard Key

Section titled “Rotate Your WireGuard Key”

Rotating your WireGuard key issues you a new Mullvad profile, which may give you a new IP address. This can help if a website is blocking you based on your current IP.

  1. Open the Obscura app

  2. Navigate to the Settings tab

  3. Under Network, click Rotate WireGuard® key
