Troubleshooting

Fexyn VPN won't connect on Windows

Work through these in order. Most disconnects are fixed by the first three checks.

First, the quick checks

Is the internet up at all? Open a browser and visit a known-good site without the VPN. If that fails too, the issue is upstream, not Fexyn.
Restart the app. Close Fexyn from the system tray, wait five seconds, and open it again. Transient connection state issues clear on restart in most cases.
Sign out and back in. If your session token has expired the app may show authentication errors. Sign out from settings and sign in again to refresh.
Reboot the helper service. Restarting Windows resets the helper service and the Wintun driver state — heavy-handed but reliable when something has wedged at the kernel level.

Try a different server

Pick another country or city from the server list and connect again. A single server might be overloaded, briefly unreachable from your route, or undergoing maintenance. If a second server connects, the first one is the issue and you can keep using the working one.

Check status.fexyn.com if multiple servers fail in a row — there may be an active incident.

Switch protocol

Fexyn ships three protocols and rotates between them automatically, but the rotation order isn't always right for your network. Pin a protocol from the app settings and try again.

Fexyn Bolt (WireGuard) failing? WireGuard is UDP-only. Some networks (corporate Wi-Fi, some hotels, some airline Wi-Fi) block outbound UDP entirely. Switch to Stealth or Secure. About WireGuard on Fexyn.
Fexyn Stealth (VLESS Reality / XRay) failing? Stealth is the right pick for restrictive networks but still depends on TLS 1.3 reaching the handshake host. If your network blocks TLS 1.3 outbound (rare), only OpenVPN will connect. Try a different server first; the handshake host is server-specific. About VLESS Reality on Fexyn.
Fexyn Secure (OpenVPN) failing? OpenVPN over TCP/443 connects on the most restrictive networks. If even OpenVPN fails, the network is almost certainly blocking VPN traffic by signature, not just by port. About OpenVPN on Fexyn.

Windows firewall and security software

Windows Defender Firewall asks once whether to allow Fexyn on private and public networks. If you said no, Fexyn can't open the tunnel. To fix:

Open Windows Security → Firewall & network protection → Allow an app through firewall.
Find Fexyn VPN in the list and check both Private and Public.
Save and try connecting again.

Third-party antivirus and "internet security" suites (Norton, Kaspersky, ESET, etc.) sometimes wrap the network stack in their own firewall and block VPN drivers. If connecting works after temporarily disabling the third- party suite, add Fexyn to its allowlist rather than leaving security disabled.

Captive portals and public Wi-Fi

Hotels, airports, coffee shops, and conference Wi-Fi usually require you to accept terms or log in via a captive portal in your browser before any traffic flows. Fexyn can't bypass a captive portal — the portal sits between you and the internet.

Disconnect the VPN.
Open a browser and go to any HTTP site (not HTTPS — the portal needs to redirect you). Most networks redirect to the portal automatically.
Complete whatever the portal asks for.
Reconnect the VPN.

Account, plan, and rate-limit messages

The app surfaces a few specific messages that look like connection errors but aren't:

Trial ended. The 7-day trial has expired. Pick a plan on fexyn.com/pricing to keep going.
Subscription paused. Payment failed and the dunning grace window has closed. Update your payment method from the dashboard.
Device limit reached. Your plan's simultaneous-connection cap is hit. Sign out of an old device from the dashboard, or upgrade.
Email not verified. Click the verification link in your inbox before connecting.
Rate limited. Too many connect attempts in a short window. Wait a minute and try again. This protects shared infrastructure from runaway clients.

What we won't promise

Some networks (national-level filters, certain ISPs in certain regions, some highly-locked corporate networks) block VPN traffic so aggressively that no current protocol reliably gets through. Fexyn Stealth is the strongest option in our stack and we keep tuning it, but no VPN can honestly guarantee universal connectivity. If nothing works on your network, the trial costs you nothing and the 30-day money-back guarantee covers the first paid period.

When to contact support

If you've worked through the steps above and Fexyn still won't connect, email support@fexyn.com with the following — that's the minimum information support needs to help you faster:

Which Windows version (10 or 11) and 32 / 64-bit
The Fexyn app version (visible in app settings)
Which protocols you tried (Bolt / Stealth / Secure) and which servers
The country and ISP you're on
What the app shows when the connection fails
Whether other apps reach the internet without the VPN

Don't send screenshots that include recovery codes, passwords, or session tokens. We don't need them to diagnose connection issues.
