Why does my VPN keep disconnecting?

Why VPNs Are Usually Easy to Fix

One good thing about virtual private networks (VPNs) is that when they don’t work, the problem is almost always solvable without technical training. Although it’s aggravating when your VPN randomly drops your connection, the chances are good that you can handle the issue yourself without getting tech support involved.

If your VPN is repeatedly disconnecting from the server, I recommend dealing with the problem immediately. When you have your kill switch on—as good cybersecurity habits dictate—VPN drops will kick you off the internet. Without that feature enabled, it’ll expose your real identity and location online. That’s not a big deal if you’re just aiming to, say, stream an international sporting event, but it could be an existential issue if you’re using the VPN as a workaround against government censorship.

Either way, you can address the issue by working through the eight troubleshooting steps below and checking whether they’ve solved your problem.

8 Reasons Your VPN Keeps Disconnecting

I’ve organized these root causes in ascending order of how much effort the solution takes. Try the easier fixes before moving on to the more complex or expensive ones.

1. You’re using the VPN on too many devices at once

Most VPNs limit the number of devices you can connect simultaneously on a single subscription. Some services (e.g., Surfshark) claim to offer unlimited simultaneous connections, but they’ll still cut you off if they see signs of abuse.

What to do:

1. Count how many phones, computers, or smart TVs already have the VPN running.
2. Pay attention to devices where the VPN is set to auto‑connect on startup—you may have missed that it’s running.
3. Disconnect the VPN on one of those devices and try again on the new one.

2. Your VPN server is slow or overloaded

The problem often rests with the server you’re trying to connect to. Providers regularly shut down servers for routine maintenance, and a server can be technically online but overloaded or physically far away, causing time‑outs.

What to do:

1. Disconnect the VPN.
2. Reconnect to the same location on a different server.
3. If the new server has the same problems, try another location (unless you need an IP address in a specific country).

3. You’re using an unstable VPN protocol

A VPN protocol is the set of instructions at the heart of everything a VPN does. Not all protocols are the same. For example, OpenVPN over TCP prioritizes speed over connection stability, causing more frequent disconnections. Some networks also block certain protocols (see #8).

What to do:
Switch to a more stable protocol such as WireGuard, OpenVPN over UDP, or IKEv2. You can almost always find the protocol options on the Settings page of your VPN app.

4. Power‑save settings are interfering

A VPN almost always runs in the background. In some cases, a device’s battery‑saver settings might shut down the VPN to conserve power.

What to do:
Turn off power‑save mode (and consider plugging in the device while you’re troubleshooting).

5. Your internet connection isn’t stable

Your VPN needs to pass traffic through an ISP like any other online app—it just encrypts that traffic first. If your home internet is flaky, the VPN will be flaky, too.

What to do:

1. Check whether you have problems with your regular internet connection.
2. Reset your modem (turn it off for at least 10 seconds, then power it back on).
3. If the issue persists, wait a few minutes to see if the ISP’s service improves.

6. Another program is interfering with the VPN

Other security programs frequently cause VPN disruptions. Examples:

• An office VPN that conflicts with a personal VPN.
• Antivirus or firewall software blocking VPN ports.

What to do:
Configure the firewall/antivirus to allow traffic through the port used by your VPN protocol, or temporarily disable the conflicting program.

7. Your software is out of date

Out‑of‑date software can cause compatibility problems. Updating also improves security, so it’s a win‑win.

What to do:

1. Update your VPN client.
2. Update your operating system.
3. (Optional) Update your router firmware—access the router’s control panel by entering its default IP address into your browser’s URL bar.

After updating, try connecting again.

8. Your network or ISP is blocking VPN traffic

Sometimes the problem originates with the network you’re on, not the VPN or your device. Offices, schools, and even entire countries (e.g., China) may block VPN traffic.

What to do:

1. Enable any obfuscation or stealth features built into your VPN.
2. Connect to a server outside the censored location.
3. If you’re in a country where VPNs are illegal or heavily restricted, consider contacting your VPN provider for a custom configuration (some providers—e.g., Proton VPN—offer this service).

How to Handle Persistent VPN Disconnections

If you still find your VPN disconnecting mid‑session, you may be dealing with a rare issue that isn’t covered in the usual troubleshooting list. In that case:

1. Contact VPN Support – Reach out to your VPN provider’s support team.
2. Follow Their Recommendations – Implement any steps they suggest.
3. Use Live Chat if Possible – Speaking with a live support technician lets you quickly convey what you’ve already tried and get real‑time assistance.
