So, you’re ready to hack the planet (ethically, of course), but your TryHackMe VPN just won’t connect. Annoying, right? You click connect. You wait. And… nothing. Or maybe you get a weird error message that looks like robot poetry. Don’t worry. This is a super common problem. And the fix is usually simple.
TL;DR: If your TryHackMe VPN isn’t connecting, check your internet, download a fresh config file, and make sure OpenVPN is installed correctly. Disable conflicting VPNs and firewalls if needed. Most issues come from expired configs, wrong credentials, or firewall blocks. Follow the steps below and you’ll be connected fast.
First Things First: Stay Calm
VPN issues feel scary. Especially when you’re new. But most of the time, the solution takes less than 10 minutes.
TryHackMe uses OpenVPN for access to its labs. If something goes wrong, it’s usually one of these:
- Expired or wrong config file
- Wrong login credentials
- Firewall blocking connection
- Another VPN interfering
- Outdated OpenVPN client
Let’s break it down step by step.
1. Check Your Internet Connection
This sounds obvious. But check it anyway.
- Can you browse websites?
- Is your connection stable?
- Are you on public Wi-Fi?
Public Wi-Fi networks often block VPN connections. Schools. Airports. Offices. They don’t love VPN traffic.
If you are on public Wi-Fi, try:
- Switching to mobile hotspot
- Connecting from home Wi-Fi
- Restarting your router
Sometimes the simplest fix works.
2. Download a Fresh VPN Config File
This is the number one fix.
Your TryHackMe VPN config file can expire. Especially if you haven’t used it in a while.
Here’s what to do:
- Log in to TryHackMe.
- Go to Access.
- Download a new VPN configuration file.
- Delete the old one.
- Try connecting again.
That’s it.
If your old file expired, this will fix it instantly.
3. Run OpenVPN Correctly
This is important. Especially on Windows.
On Windows:
- Right-click OpenVPN
- Select Run as Administrator
If you don’t run it as admin, it might fail silently. Which is super confusing.
On Linux (Kali, Ubuntu):
Use this command:
sudo openvpn yourconfig.ovpn
Notice the sudo. Without it, it won’t work properly.
On Mac:
- Make sure Tunnelblick or OpenVPN Connect is installed properly
- Allow permissions when prompted
Permissions matter more than you think.
4. Double-Check Your TryHackMe Credentials
When OpenVPN asks for a username and password, use:
- Your TryHackMe username
- Your TryHackMe password
Not your email. Not your system password.
If you recently changed your password, your VPN login changes too.
Getting authentication errors like:
AUTH_FAILEDAuthentication failed
That usually means wrong credentials.
Try logging into the website again to confirm your password works.
5. Disable Other VPNs
This is a big one.
If you already have:
- NordVPN
- ExpressVPN
- ProtonVPN
- Any built-in system VPN
Turn it off.
Two VPNs running at the same time = chaos.
They fight for control over your network routes. And TryHackMe loses.
Disconnect everything. Then try again.
6. Check Your Firewall and Antivirus
Sometimes your own computer blocks the VPN.
Firewalls are overprotective. Like a guard dog that barks at everyone.
Try this:
- Temporarily disable your firewall
- Temporarily disable antivirus
- Try connecting
If it works, you found the problem.
Important: Turn protection back on after testing. Then add OpenVPN as an exception.
On Windows:
- Go to Windows Defender Firewall
- Allow an app through firewall
- Add OpenVPN
On Linux, check your ufw status.
Simple command:
sudo ufw status
7. Update OpenVPN
Old software causes weird issues.
Check your OpenVPN version:
openvpn --version
Then compare it with the version on the official OpenVPN website.
If yours is old:
- Uninstall it
- Download the latest version
- Install fresh
Restart your computer after installing.
Yes. Actually restart it. Not sleep. Not close the lid. Restart.
8. Are You Connected But Nothing Loads?
This is sneaky.
Your VPN might say Connected. But you can’t access any TryHackMe machines.
Here’s what to check:
- Did you start the machine on the TryHackMe website?
- Did you wait for it to finish booting?
- Are you using the correct IP address?
Also try pinging the machine:
ping 10.x.x.x
If there’s no response, your VPN tunnel may not be working correctly.
Disconnect and reconnect.
Sometimes the first connection attempt fails halfway.
9. DNS Problems
Sometimes your system uses the wrong DNS server.
This can break lab access.
Quick fix:
- Restart OpenVPN
- Flush DNS cache
On Windows:
ipconfig /flushdns
On Linux:
sudo systemd-resolve --flush-caches
Small step. Big difference.
10. Look at the Error Message
Yes, I know. Nobody likes reading logs.
But error messages tell you everything.
Common errors:
- TLS Handshake Failed – Usually firewall or blocked network
- AUTH_FAILED – Wrong credentials
- All TAP-Windows adapters in use – Adapter issue on Windows
- Cannot resolve host address – DNS problem
If you see a TAP adapter error:
- Reinstall OpenVPN
- Repair TAP driver
11. Restart Everything
This sounds silly.
But do it properly:
- Close OpenVPN
- Restart your computer
- Restart your router (if possible)
- Download fresh config
- Reconnect
This fixes more issues than you think.
12. Still Not Working?
If nothing helps, try this checklist:
- Are TryHackMe servers having issues? Check their Discord.
- Is your subscription active?
- Did you select the correct region?
- Are you behind corporate firewall restrictions?
Corporate networks often block OpenVPN traffic.
If you’re in an office environment, try connecting from home.
Pro Tips for Future You
Once you’re connected, keep things smooth.
- Always download a new config when starting a new session
- Keep OpenVPN updated
- Don’t run multiple VPNs
- Run as administrator on Windows
- Save common commands in a text file
Small habits prevent big headaches.
Final Thoughts
VPN issues feel technical. And scary. But they are usually simple.
Most TryHackMe VPN problems fall into three buckets:
- Expired config
- Wrong permissions
- Network blocking traffic
That’s it.
You don’t need to be a network engineer. You just need patience. And maybe a fresh config file.
Once you’re connected, you’re back in the lab. Scanning ports. Capturing flags. Learning real skills.
And next time your VPN fails?
You’ll smile.
Because now you know exactly what to do.
