Overview of this error

Zoom error 1001 occurs when you attempt to join a meeting or webinar but are unable to connect due to an issue with:

  1. The host’s firewall settings.
  2. Inadequate permissions.
  3. Incorrect settings in the host’s security software.
  4. It can also occur if the host has enabled two-factor authentication but hasn’t provided all participants with the necessary code.

Let’s look at solving this error in detail.

How to Fix Zoom Error Code 1001?

Sign out of all Zoom accounts on all your browsers and all of your devices

Start by signing out of all your Zoom accounts on all your browsers and devices. A sign-out usually fixes this error code – we did this exact step for a client this morning and it worked!


Sign out of your student or university account and sign in to your organizational account

Many businesses and schools have upgraded licenses of Zoom that offer extra features – but if you’re no longer part of the company or school where they purchased it from down the line, un-linking your account could do the trick.

To make things easy on yourself in the future, consider creating a separate non-personalized account for those purposes!

Log out of any existing accounts associated with your email. Then sign into the account that was provided by your organization or institution using its unique link.

Once logged in check for an email confirmation and click it to “Switch to a new account.”

After accepting the terms and conditions, restart Zoom.

Restart your device

If you are using a mobile device, turn it off and then turn it back on again after waiting for a few minutes. If you are using a laptop or PC, then restarting will also help in most cases. After restarting your device, try joining the meeting again and see if it works this time around.  

Disable any security software

You’ll need to temporarily disable or pause your security software—whether that’s antivirus software or a firewall—while using Zoom.

We recommend disabling any security software before joining a meeting and then re-enabling it when you’re done. 

If disabling your security software doesn’t help, try temporarily disabling your VPN connection as well.

Many VPNs use their DNS servers, which can cause problems with Zoom connections if they aren’t configured correctly.

Update your Zoom version

In all likelihood, the version of Zoom that you have installed is no longer supported by the company and needs to be updated for it to work properly.

The easiest way to do this is by going directly to the Zoom website and downloading the latest version of their app onto your computer or mobile device.

At this time of writing:

Windows: Version 5.13.7 (12602) (64-bit)

MacOS: Version 5.13.7 (15481)

Once the download is complete, simply open up the new version of the app, reinstall the application, and try restarting your meeting again. 

Check your firewall settings

Most firewalls allow you to specify which programs are allowed to connect through them, so if Zoom is blocked, then you should add it as an exception for it to work properly.

Once the exception has been added, try joining the call again and see if that fixes the issue.
