Zoom has become a lifeline for individuals and businesses looking to connect virtually for work and pleasure. The user-friendly interface allows seamless meetings and webinars. However, like any other technology, Zoom is also not immune to issues.

We’ve all experienced a black screen, a silent video and error messages we can’t discern. These are some annoying issues that may incur but are extremely common, and that means they’re easy to fix. Here’s how to fix common Zoom problems quickly and easily.

#1. Not able to connect to Zoom

Let’s begin with the most common problem: You enter your Zoom ID and password and click on a meeting link, but are unable to enter the room. The most common causes for this are firewalls and pop-up blockers or virus protection software.

Here’s what you can do:

Solution 1: Disable Firewall

  • Look for Windows Security and open Zoom
  • Click on Firewall & network protection
  • Click Allow an app through the Firewall
  • Click Change Settings
  • Look for Zoom Video Conference and cross Private and Public
  • Click OK

If the issue doesn’t resolve, disable the Firewall, but only temporarily. Then,

  • Go back to Firewall & network protection
  • Select active network
  • Slide Microsoft Defender Firewall to Off

Note: Change this back after the Zoom call.

Solution 2: Disable Virus Protection

Another method is to turn off virus protection.

On Windows,

  • Search Windows Security and open Zoom
  • Click Virus & Threat protection
  • Beneath Virus & threat protection settings, click Manage settings
  • Turn Real-time protection to Off

After this, re-enter the Zoom meeting; you should be able to access it now. 

#2. Audio not working

Lack of audio is another common problem users face. Most often the mute button is to blame. The easiest fix is to simply click the microphone button you’ll see on your screen to unmute.

To avert this problem completely, here’s what you can do:

Solution 1: Before joining a meeting

  • Log in to the Zoom app
  • Click Profile picture>Settings
  • Click Audio tab
  • Click Test Speaker in the Speaker section. If nothing is audible, select another speaker using the drop-down menu or adjust the Volume.
  • Click Test Mic in the Microphone section. This initiates the audio; you can witness this with the movement in the Input Level bar move.

Solution 2: While joining a meeting

  • Click Test Speaker and Microphone. A pop up window appears to test your speakers.
  • If no ringtone is heard, select No, Try Another Speaker. Click Yes
  • If no audio replay is heard, click No, Try Another Microphone. Click Yes to confirm
  • Click Join with Computer Audio to return back.
  • It’s also possible your microphone has become disconnected, or something is blocking it. Another common cause of audio issues is that in your computer’s settings menu, a different audio source has been selected accidentally (common if you switch among the computer’s internal mic, external microphones or headphones often). Check what audio source the computer is using, and re-set it to a more appropriate source if needed.

#3. Video not working

If the screen appears black, look for anything accidentally covering your camera (including having a privacy shutter closed). Sometimes it’s possible a webcam has tilted or been knocked over. If there’s no physical problem with a blockage, make sure that any cables are still connected and not loose. If that fails:

Solution: Check Settings and Set permissions

  • Open Zoom app
  • Click New Meeting
  • Click ^ on video button
  • Choose Settings
  • Click on video on the left side

However, if nothing is visible, see what device you are using. If you are working on MacOS or Windows 10, set app permissions to use the camera and microphone.

In Windows,

  • Go to Start menu>Privacy Settings
  • Select camera from the left hand side
  • Toggle to turn on Allow desktop apps to access your camera
  • Scroll and confirm permission for Zoom app. Tick the box against Zoom.

In MacOS,

  • Go to System Settings>Security and Privacy
  • Click lock. Enter password
  • Click on “Camera”. Check web browser, and Zoom

If the issue continues, try uninstalling Zoom and installing it again.

#4. Freezing/Lagging during the meeting

Freezing and lagging means your internet connection is either weak or fluctuating. Also, something may be draining your internet speed. It could be background downloads or your spouse streaming Amazon Prime.

Solution 1: Make sure your internet speed is at sufficient levels to attend one-on-one or group meetings. Test it on Upgrade to 5GHz if possible.

Solution 2: Move to another location.

Solution 3: Change Zoom settings. Disable the “Touch Up My Appearance” or HD option in a video setting.

Solution 4: If freezing/lagging continues, disable your webcam and continue with an audio-only call. Ideally, this should settle your issue; however, in case it fails, then do two things. Restart your router or Contact your ISP.

#5. Echoing Audio

It is yet another issue that may happen due to a participant using both desktop and phone at the same time or if your phone and PC speakers are close together.

Solution 1: Ask the participant using two devices to mute one.

Solution 2: Ask people to move their devices apart or one of them to leave the meeting room.

Solution 3: Use a proper microphone

#6. Not receiving emails/notifications from Zoom

Generally, Zoom sends emails and notifications on activation or when you’re invited to meetings, or the status is updated or changed. If you haven’t received them, check your spam folders.

Solution 1: If you are working for an organization that manages the Zoom account, ask them to add and allow the Zoom IP addresses.

Solution 2:

In Gmail:

  • Select More>Spam
  • Search OR
  • Select More>All Mail
  • Search for

#7. Screen sharing not working

When sharing screen turns troublesome, fix it with these simple troubleshooting methods.

  • Check your app version and upgrade if it is old.
  • Remove caches and cookies (for web users)
  • Restart the device or browser
  • Enable screen recording (for macOS version 10.15 Catalina and higher users)

Or enable sharing and/or change settings.

Solution 1: Enable screen sharing

As a host, you enabled screen sharing, but it stops when the meeting commences and you receive a message: You are restricted from screen sharing in this meeting.

To enable it,

  • Go to the web portal Settings page
  • Cross Disable screen sharing when guests are in the meeting

However, if screen sharing is grayed out, it means it has been locked. Contact Zoom admin for help.

Solution 2: Adjust default screen sharing

  • Open Zoom
  • Click Settings>Meetings
  • Select screen sharing and enable it

You get multiple options here: How many number of participants can share, who can share (host or all participants), who can initiate sharing, and disable sharing when meeting with the guests. Select what works for you. But remember, these adjustments apply to all future meetings until re-adjusted.
