Mullvad VPN Not Connecting or Stuck on Connecting
Quick answer
If Mullvad hangs on 'Connecting' and then shows 'Blocking internet', your network is usually blocking the WireGuard connection or one server is down. Switch to another city, change the WireGuard port or turn on UDP-over-TCP/QUIC under Anti-censorship, and log out and back in if your keys are stale.
Most likely fix: Switch to a different location
How to fix it
Try these in order — the most common fix is first.
1. Switch to a different location
- Tap Switch location
- Pick another city or country, or another server in the same city
- Users report one location failing while a neighbouring one connects instantly

- Open Settings > VPN settings > Anti-censorship
- Set WireGuard port to Automatic, 51820, 53 or a custom port
- If it still fails, choose UDP-over-TCP (port 443) or QUIC obfuscation

- Open the Account screen
- Tap Log out
- Log in again with your account number to register fresh WireGuard keys
Did this fix it?4. Disable conflicting software

- Reconnect

Symptoms
The app keeps cycling through 'Connecting', then shows a red padlock and 'BLOCKING INTERNET'; no websites load while it tries.
Why it happens
- Your ISP, mobile carrier or Wi-Fi network blocks VPN/WireGuard ports
- The selected server or location is temporarily down
- Stale WireGuard key or device registration after reinstalling
- Another VPN, firewall or antivirus is interfering
- Outdated app version (older apps relied on OpenVPN servers that no longer exist)
