Something not working? You're in the right place. Find your issue below and follow the fix.
First: Run System Check
Before diving into specific issues, try Kolab's built-in diagnostic tool:
System Check automatically tests your camera, microphone, speakers, and browser compatibility. It catches 80% of issues and tells you exactly what to fix.
Run this before every session, especially if you're on a new device or network.
Audio Issues
I can't hear anyone
Most likely: You're too far away on the canvas.
Fix:
- Move closer to other participants on the canvas
- If you still can't hear, check your speaker/headphone selection
- Check your system volume (not just browser volume)
- Try a different audio output device
Still stuck? Ask in chat if others can hear - the issue might be on someone else's end.
No one can hear me
Check the basics:
- Look at your microphone icon - are you muted?
- Check that the correct microphone is selected
- Speak and watch the audio level indicator - does it move?
If the indicator doesn't move:
- Close other apps that might be using your mic (Zoom, Teams, Discord)
- Check browser permissions for microphone
- Try selecting a different microphone
- Refresh the page
If the indicator moves but people can't hear you:
- You might be too far away - move closer to others
- Ask others if they can see your audio indicator
There's an echo
Cause: Your microphone is picking up audio from your speakers.
Fix:
- Use headphones - This almost always solves it
- If you can't use headphones:
- Turn down your speaker volume
- Move your microphone away from your speakers
- Use a directional microphone if you have one
My audio is choppy or robotic
Cause: Usually a network issue.
Fix:
- Close other apps using bandwidth (streaming, downloads)
- Move closer to your Wi-Fi router
- Try a wired ethernet connection
- Ask others if they're experiencing the same thing (might be the other person's connection)
I hear myself echoing
Cause: Someone else in the session doesn't have headphones.
Fix:
- Ask in chat if everyone can use headphones
- The person causing the echo should lower their speaker volume
- If you can identify who it is, let them know privately
Video Issues
My camera won't turn on
Check the basics:
- Is another app using your camera? (Close Zoom, Teams, FaceTime, etc.)
- Does your laptop have a physical camera cover? (Slide it open)
- Did you allow camera permission in your browser?
Browser permission check:
Chrome: Click the lock icon in the address bar → Site settings → Camera → Allow
Firefox: Click the permissions icon (left of URL) → Camera → Allow
Safari: Safari menu → Settings for this Website → Camera → Allow
Still not working?
- Try refreshing the page
- Try a different browser
- Restart your computer
- Try an external webcam if you have one
My video is dark
You need more light on your face:
- Face a window (during daytime)
- Add a lamp in front of you (not behind)
- Avoid sitting with a bright window behind you
My video is blurry or pixelated
If blurry (out of focus):
- Clean your camera lens
- Check if your camera has auto-focus
- Try moving closer or further from the camera
If pixelated (low quality):
- Close bandwidth-heavy apps
- Check your internet speed (speedtest.net)
- Move closer to your router
- Try a wired connection
My video freezes
Cause: Network bandwidth issue.
Fix:
- Close other apps using internet
- Close unnecessary browser tabs
- Move closer to your router
- Try a wired connection if possible
- Consider turning off your video temporarily
Navigation Issues
I can't find anyone
You're probably too zoomed in or far away:
- Zoom way out - scroll down on your mouse or pinch on trackpad
- Look for clusters of participant videos
- Check the minimap (usually in a corner)
- Ask in chat where everyone is
I can't move around the canvas
Make sure you're clicking in the right place:
- Click on empty canvas space (not on videos or objects)
- Then drag to pan
If nothing responds:
- Try clicking somewhere else
- Refresh the page
- Try a different browser
Everything is too small / too big
You need to adjust your zoom:
- Zoom in: Scroll up or pinch out
- Zoom out: Scroll down or pinch in
- Reset zoom: Press
0on your keyboard
The canvas is laggy
Performance issue - try these:
- Close other browser tabs
- Close other applications
- Refresh the page
- Try Chrome (often fastest for Kolab)
- If you have many participants, that's normal - it takes more power
Connection Issues
The page won't load
- Check your internet connection
- Try refreshing the page
- Try a different browser (Chrome or Firefox recommended)
- Disable VPN if you're using one
- Disable browser extensions temporarily
- Clear your browser cache
I keep getting disconnected
- Check your internet connection stability
- Move closer to your router
- Try a wired connection
- Close bandwidth-heavy apps
- Ask your facilitator if others are having issues
"Connection error" message
- Check your internet connection
- Refresh the page
- Try a different browser
- Clear your browser cache
- Contact your facilitator if the problem persists
Browser Issues
Which browser works best?
Recommended: Chrome or Firefox (latest versions) Works: Edge, Safari (may have some limitations) Not supported: Internet Explorer
If you're having issues, try switching to Chrome.
Browser says "site not secure" or blocks access
- Make sure you're using the correct link
- Try a different browser
- Check if your organization's firewall is blocking the site
- Contact your IT department if on a corporate network
Still Stuck?
Ask for help during the session
- Use chat - Type your issue, someone may help
- Raise your hand - Get the facilitator's attention
- Send a private message - To the facilitator if that option exists
General troubleshooting steps
If you've tried everything:
- Refresh the page - Fixes many issues
- Try incognito mode - Rules out extension problems
- Try a different browser - Chrome usually works best
- Restart your browser - Clears out memory issues
- Restart your computer - Nuclear option, often works
