Below are listed current known issues within Virtual Classroom. If you are experiencing one of these symptoms, please click on the tab to review the solution. 

General Issues

I Cannot Enter the Meeting

The Symptom:

A user can move past the Enter the meeting button, but gets stuck on a blank screen.

The Solution:

  • Open the meeting in Chrome or Firefox. If you’re in one, try the other.
  • Ensure the browser version is up to date. Most browsers will update automatically (or have an option to do so). To check for pending updates, view Chrome instructions or Firefox instructions.
  • Quit your browser application and re-open.
I am Receiving an "Internal Server Error" Message

The Symptom:

Users encounter an “Internal Server Error” message when trying to enter the meeting.

The Solution:

  • Open the meeting in Chrome or Firefox. If you’re in one, try the other.
  • Refresh the page.
  • Wait a few minutes and try re-entering the meeting.
I Was Kicked Out of a Meeting

The Symptom:

Users are randomly denied access to part of a meeting or kicked out entirely, without action on their part or the part of a moderator.

The Solution:

Usually when a user is kicked, it is most likely due to the browser not being responsive for a period of time. To troubleshoot:

  • Reload the page.
  • Close and reopen the chat window.
  • Open an Incognito/Private browser tab.

Playback Issues

Missing Meeting Playback

The Symptom:

A user can’t find a meeting recording.

The Solution:

We've found that many users forget to tap the Record button. If you are sure you clicked Record, you can submit a support ticket with the following information, and we can investigate the issue further: 

  • Meeting URL
  • Meeting name
  • Date/Time of session
  • Name of user who scheduled meeting
  • Instructor's name
Processing Delay

The Symptom:

A meeting takes a long time to process.

The Solution:

  • Wait for 1-2x the meeting duration for the processing to complete, as this is the normal duration.
  • After waiting and meeting still has not processed, please submit a support ticket and we can investigate further. 
Poor Audio/Video Quality

The Symptom:

The audio or video playback quality is unexpectedly poor.

The Solution:

  • The recording quality will match the audio and video quality of the original meeting. If the quality was poor during the meeting itself, then you may investigate your network connection quality and speed for future meetings.
  • If the recorded meeting quality is significantly poorer than the quality experienced during the meeting, please submit a support ticket and we can investigate the issue further.
Missing Elements

The Symptom:

Parts of the meeting that should have been captured, such as a screen-share, webcam, or presentation, don’t appear in the recording playback.

The Solution:

Contact submit a support ticket and we will investigate the issue further. In your message, be sure to include the following:

  • Meeting URL
  • Meeting name
  • Date and time of session
  • Name of user who scheduled meeting
  • Instructor's name
Recording Sync Issues

The Symptom:

At times, Virtual Classroom meetings may have the audio and video slightly out of sync during the live meeting due to network latency and congestion.

The Solution:

  • Experiment with alternative audio and video devices, such as wired headsets, microphones, and webcams. Bluetooth and wireless devices have been known to sometimes introduce a slight delay.

Webcam and Microphone Issues

Total Webcam Failure

The Symptom:

 The webcam fails. You and/or other participants are unable to see your face.

The Solution:

  • Make sure you are not sharing webcam in another app (Hangouts, Webex, etc) and close the apps if they are in use.
  • Use this website service to verify that your browser has permission to use webcam.  If you do not have permission, you will need to change the webcam permissions in FireFox (Options > Privacy & Security > Permissions > Camera) or Chrome (Settings > Advanced > Privacy & Security > Content Settings > Camera)
  • Try a different browser. We recommend Chrome or Firefox.
  • Try using webcam in another application (Hangouts, Zoom, Webex, Skype, your computer's camera, etc.) to verify that the webcam works.
  • If you see a popup message stating “ICE negotiation failed”, try turning off Windows firewall (on PCs), disconnecting any VPN connections, turning off virus network protection, and disabling extra browser plugins/extensions.
  • Check to see if your CPU is running very hot. If your keyboard feels warm, it may be because your CPU is running hard to keep up with the webcam and other memory intensive applications. Identify these applications and/or browser tabs with Task Manager on PC and Activity Monitor on Mac, and close them down to relieve your computer.
Poor Webcam Quality

The Symptom:

Other users say your webcam quality is poor.

The Solution:

  • Check your CPU usage on your computer, with Task Manager on a PC and Activity Monitor on a Mac. If it’s high, it may help to close some other applications and/or browser tabs.
  • Check your upload speed with this website's service to ensure it meets the required bandwidth speed for your session. Please refer to this article when calculating the bandwidth needed for a Virtual Classroom meeting.
Total Microphone Failure

The Symptom:

  1. The Echo Test fails when you join the meeting space.
  2. Other participants cannot hear you.
  3. You see a popup message that says “ICE negotiation failed”.

The Solution:

  • Check for other apps that use the microphone (Google Hangouts, Webex, etc.) and close those apps if they are in use.
  • Use this website’s service to check that your browser has permission to use the microphone. If the browser doesn’t have permission, you need to change the microphone permissions in FireFox (Options > Privacy & Security > Permissions > Microphone) or Chrome (Settings > Advanced > Privacy & Security > Content Settings > Microphone)
  • Try a different browser. We recommend Chrome or FireFox.
  • You may have multiple microphones connected to your computer, such as a built-in microphone on a laptop and a pair of headphones with an inline mic. The default microphone may not be the one Virtual Classroom is listening to, so check your browser for default settings. (in Chrome you change the default in Settings > Privacy and Security > Content settings > Microphone, in Firefox it’s Preferences > Privacy and Security > Permissions > Microphone).
  • Try selecting a different microphone in the menu in Bongo.
  • If you see the “ICE negotiation failed” message, try turning off Windows firewall (on PCs), disconnecting any VPN connections, turning off virus network protection, and disabling extra browser plugins/extensions.
Poor Audio Quality

The Symptom

Other participants report poor audio quality from your microphone.

The Solution:

  • Reposition the microphone closer to your face, as some microphones listen more in certain directions.
  • Connect a different microphone if available.
  • Check your upload speed with this website's service to ensure it meets the required bandwidth speed for your session. Please refer to this article when calculating the bandwidth needed for a Virtual Classroom meeting.

Administration and Presentation Issues

Meeting Setup Issues

The Symptom:

As an instructor, the time-setting widget or the meeting’s invite list may break.

The Solution:

  • Impersonate the user (or instructor) to verify the meeting's setup matches the users expectations. Sometimes the features act differently when the user is acting in a different role.
Screen Sharing Issues

The Symptom:

A user in a Virtual Classroom meeting tries to share their screen and the meeting fails to turn it on for them, or the meeting shares something different from what the user expects.

The Solution:

  • Ensure that you have no popups enabled.
  • When using Google Chrome specifically, make sure to select ‘Your Entire Screen’ in the popup it gives you when turning on screen share. This allows the meeting to share exactly what you see instead of sticking to a specific window.
Microsoft application (PowerPoint etc.) issues when screen sharing

The Symptom:

Using hardware graphics acceleration may cause issues (click here for more information).

The Solution:

If you haven’t installed Bongo Screenshare Extension for Chrome, perform the following steps to make sure it’ll work for you:

  • Install the extension from here.
  • Restart your browser after installing.
  • Verify the extension is enabled by going to Chrome’s ellipsis menu > More Tools > Extensions and checking the toggle switch on Bongo Screenshare Extension.
Presentation Delay

The Symptom:

Presentation slides take longer than they should to progress from one to another.

The Solution:

  • If the presentation wasn’t originally uploaded as a PDF, try saving the presentation as a PDF (outside the meeting) and uploading the PDF version into the meeting. This solves the speed issue for most users.
Chat System Delay

The Symptom:

New chat messages don’t display in the chat log right away, or the chat log is slow to respond to scrolling.

The Solution: 

  • Close and reopen the chat window.
  • Refresh the page.
