What to Do If Your OpenVPN Connection Keeps Dropping
A VPN that keeps disconnecting can disrupt work, video calls, and access to company resources. Frequent OpenVPN drops often result from weak internet connections, firewall interference, or configuration issues. Follow these steps to troubleshoot and stabilize your OpenVPN Connect v3 connection.

📌 Step 1: Check Your Internet Connection
✔ If your internet is unstable or slow, OpenVPN may disconnect frequently.
✔ Run a test at Speedtest.net to verify speed and latency.
✔ Try browsing without the VPN to confirm if the issue is network-related.
How to Fix:
✅ Switch from Wi-Fi to a wired Ethernet connection for stability.
✅ Restart your modem and router.
✅ Move closer to your router if using Wi-Fi.
✅ A stable internet connection is essential for a reliable VPN link!
📌 Step 2: Restart OpenVPN and Your Device
✔ Close OpenVPN Connect completely.
✔ Restart your computer or mobile device.
✔ Re-open OpenVPN Connect and reconnect.
✅ A reboot clears cached sessions and resolves minor software glitches.
📌 Step 3: Change VPN Servers or Locations
✔ Some VPN servers experience heavy load or temporary outages.
How to Fix:
✅ In OpenVPN Connect, select a different server location.
✅ If your organization provides multiple .ovpn profiles, try another.
✅ Switching servers can restore stability if one endpoint is overloaded.
📌 Step 4: Enable OpenVPN Keep-Alive Settings
✔ Keep-Alive prevents your session from timing out during brief network drops.
How to Fix:
✅ Open your .ovpn file in a text editor and add:
keepalive 10 60
reneg-sec 0
✅ Save and re-import the profile into OpenVPN Connect.
✅ This setting maintains the tunnel even when packets are temporarily lost.
📌 Step 5: Check Firewall and Security Software
✔ Firewalls or antivirus tools may block VPN traffic, especially UDP.
✔ Public or corporate Wi-Fi networks sometimes restrict VPN ports.
How to Fix:
✅ Add OpenVPN Connect to your firewall’s Allowed Apps list.
✅ Disable VPN blocking in antivirus or Windows Defender.
✅ If issues persist, switch the connection protocol (see next step).
✅ Allowing OpenVPN through security software ensures uninterrupted connectivity.
📌 Step 6: Switch from UDP to TCP Protocol
✔ UDP is faster but less tolerant of unstable networks; TCP offers more reliability.
How to Fix:
✅ Open your .ovpn file and find this line:
proto udp
✅ Change it to:
proto tcp
✅ Save and re-import the configuration.
✅ TCP maintains better stability on weak or congested links.
📌 Step 7: Adjust MTU Settings for Unstable Networks
✔ Packet fragmentation can cause VPN disconnects.
How to Fix:
✅ Add this line to your .ovpn file:
mssfix 1400
✅ Save and re-import the configuration.
✅ Lowering MTU helps prevent dropped packets and improves consistency.
📌 Step 8: Contact Your IT Team or VPN Provider
✔ If the issue persists, it may be server-side.
✔ Provide details such as frequency of drops, error messages, and steps you’ve tried.
✅ Your IT team can review logs, adjust timeouts, or migrate you to a more reliable endpoint.
📌 Prevent Future VPN Disconnects
✔ Use Ethernet instead of Wi-Fi for mission-critical work.
✔ Enable Auto-Reconnect in OpenVPN Connect settings.
✔ Keep the app and configuration files updated.
✔ Use a VPN-ready router for improved throughput.
✅ A well-configured VPN ensures continuous secure access to business systems.
💡 Axio Networks Pro Tip
For business users, deploying redundant VPN servers, split-tunneling policies, and real-time network monitoring prevents disconnections and maximizes performance.
