5 Reasons Your VPN Gets Stuck Connecting

There's nothing more frustrating than watching that little spinning icon just... sit there. Your VPN is stuck connecting, and nothing seems to happen. The good news? This is one of the most common VPN problems people run into, and in most cases it's pretty easy to fix. You don't need to be a tech wizard — you just need to know where to look.

A VPN gets stuck connecting for a handful of reasons: the server you're trying to reach might be overloaded, your firewall could be blocking the connection, your internet itself might be flaky, or the VPN protocol you're using isn't playing nicely with your network. Sometimes it's something as simple as an outdated app. Let's walk through each one so you can figure out what's going on and get back online.

Why Does a VPN Get Stuck Connecting?

To understand why this happens, it helps to know a little about what your VPN is actually doing when you hit that connect button. Your VPN app is trying to establish an encrypted tunnel between your device and a remote server. That process involves a handshake — basically your device and the server exchanging security credentials and agreeing on how to communicate. If anything interrupts that handshake, the connection just... stalls.

Think of it like trying to call someone on the phone. If the line is busy, if there's interference, or if one side isn't picking up, the call never connects. Your VPN is doing something similar, just with a lot more encryption involved.

Here's the thing — most stuck connecting issues come down to five main culprits. Once you know what they are, troubleshooting becomes a lot less mysterious.

Server overload or outage is probably the most common reason. Popular VPN servers — especially free ones — can get absolutely hammered with traffic. If too many people are connecting to the same server at the same time, new connection attempts can time out. The server isn't refusing you exactly, it's just too busy to respond properly.

Firewall or antivirus interference is another big one. Your Windows Defender, third-party antivirus, or even your router's built-in firewall might see your VPN's connection attempt as suspicious and block it. This is especially common after a software update, when security settings sometimes reset to more restrictive defaults.

Protocol mismatches matter more than most people realize. VPNs use different protocols — like WireGuard, OpenVPN, or IKEv2 — to establish connections. Some protocols use specific ports that might be blocked on certain networks. If you're trying to connect from a hotel, school, or corporate network, there's a good chance some of those ports are locked down.

Your underlying internet connection being unstable is something people often overlook. If your WiFi signal is weak or your ISP is having issues, your VPN can't even get far enough to complete the handshake. The VPN app just keeps trying and never succeeds.

Finally, an outdated VPN app can cause all kinds of weird behavior, including getting stuck on the connecting screen. VPN providers update their apps frequently to fix bugs and improve server compatibility. Running an old version is asking for trouble.

How to Fix a VPN Stuck on Connecting

Alright, let's get practical. Here are the steps I'd recommend working through, roughly in order from easiest to more involved.

Step 1: Switch to a different server. This is always the first thing to try. Most VPN apps make this dead simple — just pick a different location or hit an "auto-select" button that finds the best available server. If the server you were connecting to is overloaded or temporarily down, a different one will usually connect right away.

Step 2: Check your basic internet connection. Before blaming the VPN, make sure your internet is actually working. Disconnect from the VPN entirely and try loading a website. If that's broken too, the problem isn't your VPN — it's your connection. Restart your router and modem, wait 30 seconds, and try again.

Step 3: Change the VPN protocol. Open your VPN app's settings and look for a protocol option. If you're on WireGuard, try switching to OpenVPN UDP or TCP. If you're on OpenVPN UDP, try TCP — it's slower but more reliable on restrictive networks because it uses port 443, the same port as regular HTTPS traffic, which almost never gets blocked.

Step 4: Temporarily disable your firewall or antivirus. I know, this sounds scary, but it's just for testing purposes. If your VPN connects successfully with the firewall off, you've found your culprit. You can then add your VPN app as an exception in your firewall settings rather than leaving it disabled permanently. According to the Cybersecurity and Infrastructure Security Agency (CISA), VPN software should be whitelisted in endpoint security tools to avoid exactly this kind of conflict.

Step 5: Update your VPN app. Go to your app store or the VPN provider's website and check if there's an update available. Install it, restart the app, and try connecting again. This fixes a surprising number of weird issues.

Step 6: Reinstall the VPN app. If nothing else works, a clean reinstall often does the trick. Uninstall the app completely, download a fresh copy, and set it up again. Sometimes corrupted installation files or leftover settings from a previous version are the culprit.

Step 7: Restart your device. I know, classic IT advice. But seriously — a fresh reboot clears out lingering processes that might be interfering with the VPN's network drivers. It's worth trying before you go down a deeper troubleshooting rabbit hole.

Common Situations Where VPNs Get Stuck More Often

There are certain environments where VPN connections are just harder to establish. Knowing about them can save you a lot of head-scratching.

Hotel and airport WiFi is notorious for blocking VPN connections. These networks often use deep packet inspection to identify and throttle VPN traffic. Switching to OpenVPN TCP on port 443 — or using a VPN with obfuscation features — usually gets around this. Obfuscation basically disguises your VPN traffic as regular web traffic so it doesn't get flagged.

Corporate and school networks are similar. IT departments sometimes block VPN protocols intentionally, either for security reasons or to prevent people from bypassing content filters. If you're on a managed network, you might need to talk to your IT department or use a protocol that's less likely to be blocked.

Mobile connections can also be tricky. If you're on cellular data and your VPN keeps getting stuck, it might be your carrier throttling or blocking certain traffic types. Switching protocols usually helps here too. Some carriers are more VPN-friendly than others.

One thing worth mentioning — if you're consistently having trouble connecting to VPNs, it might be worth looking at whether your current VPN provider has reliable infrastructure. According to discussions on r/VPN, a lot of stuck-connecting complaints come from users on free or budget VPN services with limited server capacity. A provider with thousands of servers gives you way more options when one goes down.

In my experience, the single biggest factor in connection reliability is the size and quality of a VPN's server network. VPNs with 6,000+ servers — like NordVPN, which VPNTierLists.com rates as S-Tier — give you so many fallback options that a stuck connection is usually solved by just switching servers. When you're on a provider with 50 servers and half of them are overloaded, you're stuck in a much harder situation.

Frequently Asked Questions

Why does my VPN connect on some networks but not others?

This almost always comes down to the network blocking certain ports or protocols. Some networks — especially corporate ones, hotels, and schools — use firewalls that restrict VPN traffic. Try switching to OpenVPN TCP on port 443, or enable obfuscation in your VPN settings if it's available. These methods make your VPN traffic look like regular HTTPS traffic, which is almost never blocked.

How long should a VPN take to connect?

Normally a VPN should connect within 5 to 15 seconds. If it's been spinning for more than 30 seconds without connecting, something is wrong. WireGuard-based connections tend to be the fastest — often connecting in under 5 seconds. If you're regularly waiting longer than that, try switching protocols or servers.

Can a VPN get stuck connecting because of my ISP?

Yes, it's possible. Some ISPs — particularly in countries with heavy internet restrictions — actively throttle or block VPN connections. If you suspect this is the case, try using a VPN with obfuscation or stealth mode enabled. These features are specifically designed to get around ISP-level VPN blocking by disguising the traffic.

Does restarting the VPN app actually help?

More often than you'd think, yes. VPN apps can sometimes get into a weird state where they're trying to connect to a server that's no longer responding, but the app hasn't timed out yet. Force-closing the app and reopening it clears that state and lets it start fresh. If the app keeps getting stuck repeatedly, that's a sign something deeper is wrong — try the protocol switch or reinstall steps.

Bottom Line

A VPN stuck on the connecting screen is annoying, but it's almost always fixable. Start with the easy stuff — switch servers, check your internet, change the protocol. If that doesn't work, look at your firewall settings and make sure your app is up to date. Most people find their issue within the first two or three steps.

If you're constantly dealing with connection problems, it might be worth upgrading to a more reliable VPN provider. One with thousands of servers and solid protocol support will give you way fewer headaches than a budget option with limited infrastructure. Based on our testing at VPNTierLists.com, NordVPN consistently handles connection reliability better than most — the NordLynx protocol in particular is both fast and stable across different network types.

Next time your VPN gets stuck, don't panic. Work through the steps, and you'll be back online in no time.
