Zoom primarily uses ports TCP 80 and TCP 443, but also TCP 8801 – 8802 and UDP 3478, 3479, 8801 – 8810. Zoom does not require any public-facing open ports to operate. It initiates the outbound connections to the Zoom servers, and uses this for all communications.Aug 10, 2020
The ports that need to be opened in Network Firewall Or Proxy Server Settings For Zoom are 80/443/8801/802. Please tell us the usage of 8801/8802. I use TCP / 8801,8802,9090 and UDP / 3478,3479.
Zoom video meetings use a combination of TCP and UDP. TCP connections are made using TLS and UDP connections are encrypted with AES using a key negotiated over a TLS connection.” The encryption that Zoom uses to protect meetings is TLS, the same technology that web servers use to secure HTTPS websites.
Zoom firewall rules
Zoom will communicate to the destination port received when the client makes its connection. The firewall should be configured to allow these return connections.
Connectivity issues with Zoom’s servers. If you are on a network with a firewall or a proxy, contact a network administrator to check your firewall and proxy settings. An antivirus software like AVG may be blocking your connection to Zoom. Disable the service and try again.
If restarting your computer does not fix the problem, and the Zoom meeting is not showing video still, then uninstall the Zoom Windows client and reinstall it on your system. When your PC restarts, download and install Zoom again. Test it now to see if the reinstallation has solved your issue of Zoom video not working.
video streaming all use TCP and simply buffer a few seconds of content, instead of using UDP since the delay is not crucial and TCP transfers can be easily accomplished over HTTP and web browsers without the need for additional plugins and software.
The App uses only outbound HTTPS for data and unicast video streaming. It uses specified multicast group addresses for UDP video streaming.
To add Zoom to McAfee Firewall, please see McAfee’s support documentation regarding preventing McAfee on Windows from blocking apps. You will need to add Zoom from the users/appdata/roaming/Zoom/bin location on your computer and select Zoom and Zoom Launcher.
Windows Security is your home to manage the tools that protect your device and your data: Virus & threat protection – Monitor threats to your device, run scans, and get updates to help detect the latest threats. (Some of these options are unavailable if you’re running Windows 10 in S mode.)
Restart your modem, router and device you’re running Zoom on – computer, smartphone. You may also update your router’s firmware, if that’s available. Check if your ISP is having temporary issues. They should have a status page or at least a social media account to communicate that.
Zoom Escaper is a free web widget that lets you add several fake audio effects to the next Zoom Call you want to ditch. The audio effects include “bad connection”, “echo”, “upset baby”, “man weeping”, “wind”, “dogs”, “construction” and even “urination”. Here’s how to use Zoom Escaper for yourself.
If the camera thinks the color temperature is the same as daylight, but you are actually getting indoor light, the photo will often come out too warm. The result will be a yellow looking photo.
Zoom may kick you out of a meeting if your software is not up-to-date. To check for updates on either a Windows or Mac computer, open the desktop app: Click your initials or pic in the upper right corner. Click Check for Updates.

Check your Internet bandwidth using an online speed test, such as nperf, Speedtest, or Comparitech. Contact your corporate IT department to check your WiFi hotspot.

I can’t join my meeting
Room connector is not enabled for this meeting: If you are using videoconferencing equipment to join a meeting hosted by a free Zoom account or an account that doesn’t have the room connector enabled, you will receive this error. Connect to the meeting using a desktop or mobile device instead.
If you must interrupt, try something like: ‘I’m sorry to interrupt, but…’. Or if there’s a particularly large group in your meeting, you could even try a hand-raising approach. It may feel like you’re back in school, but if it makes things run more smoothly at the moment, it’ll be worth it.
For sending live video streams each appliance requires the outbound UDP port range 64936-65535 to be open to the hosted streaming servers using the Real-time Transport Protocol (RTP).
In case of time sensitive applications, UDP is faster protocol as it doesn’t wait for acknowledgement from the client side and retransmission of lost packet. Little pre-fetching can be achieved in live streaming and more the buffering, the greater is media play-out delay.
|Speed||Slower than UDP||Faster than TCP|
|Broadcasting||Does not support Broadcasting||Does support Broadcasting|
Zoom decided on WebRTC’s data channel in its current SCTP implementation. They haven’t gone for the Google Chrome experiment of a QUIC data channel (which should be rather “safe” considering Google Stadia is said to be using it). … Zoom is using WebRTC. Somewhat.
With Zoom, you’re literally “Zooming.” The server receives your client’s data, the client figures out whether there’s a low-bandwidth situation or not, and adapts its video stream accordingly.
