FortiClient is a great tool for secure VPN connections. But if you’re a Mac user, you might have run into Error 104. This error can be frustrating, especially when you just need to get online quickly.

Don’t worry! We’ll explain what causes this error and how to fix it step by step. Follow along, and you’ll be back up and running in no time.

What is FortiClient Error 104?

FortiClient Error 104 usually happens when the VPN client cannot establish a connection. This can be due to several reasons:

  • Incorrect VPN settings
  • Network restrictions
  • Outdated FortiClient software
  • Conflicts with your Mac’s firewall or security settings

Now, let’s go through the solutions!

Solution 1: Check Your VPN Credentials

The most common reason for Error 104 is invalid login details. Double-check your:

  • Username
  • Password
  • VPN server address

Even a small typo can prevent the connection. If you’re not sure, contact your administrator for the correct details.

Solution 2: Restart FortiClient and Your Mac

This may sound simple, but restarting often fixes connection issues.

  1. Close FortiClient completely.
  2. Restart your Mac.
  3. Reopen FortiClient and try to connect again.

Often, this refreshes the settings and resolves Error 104.

Solution 3: Update FortiClient

Outdated software can cause connection errors. Make sure you’re using the latest version of FortiClient:

  1. Go to the Fortinet website.
  2. Download the latest version of FortiClient for Mac.
  3. Install the update and restart your Mac.

Try connecting again after updating.

Solution 4: Check Firewall and Security Settings

Your Mac’s firewall and security settings might be blocking FortiClient. Follow these steps to check:

  1. Go to System Settings → Network → VPN & Filters.
  2. Ensure FortiClient is allowed through the firewall.
  3. If you have third-party security software, try temporarily disabling it.

After making these changes, try connecting again.

Solution 5: Reset FortiClient Configuration

If nothing else works, resetting FortiClient may help:

  1. Close FortiClient completely.
  2. Go to /Library/Application Support/FortiClient.
  3. Delete the configuration files (backup first if necessary).
  4. Restart your Mac and open FortiClient.
  5. Re-enter your VPN credentials and try connecting again.

Solution 6: Check Your Internet Connection

Sometimes, the problem is not with FortiClient but with your internet connection. Try these steps:

  • Restart your Wi-Fi router.
  • Try connecting to a different network.
  • Use a wired connection instead of Wi-Fi.

A weak or unstable connection might be causing Error 104.

Solution 7: Reinstall FortiClient

If nothing else works, a fresh install might help:

  1. Go to Applications and delete FortiClient.
  2. Download the latest version from the Fortinet website.
  3. Install it, restart your Mac, and try again.
