Chromebook zoom web client not working through proxy

Error codes: N/A
Device type: Chromebook
Zoom version: web client
Details about troubleshooting steps you have already taken
-windows/chrome/web client works as expected
-chromebook with no proxy works as expected
-chromebook App works as expected

 

when using web client on a chromebook, through a proxy server, we get
"Joining Meeting Timeout or Browser restriction" error and fail to connect.

 

using the same proxy but with Windows/Chrome/web client, things work as expected.

 

taking tcp packets, we noticed zoom web client (Chromebook/chrome) has a unique behavior when a proxy server is used.
-dns queries for "zoomxxxx.xxxx.zoom.us" (*guessing host is websocket connections)
-no requests happen for either above IP address
-no requests happen for above host names through proxy

 

the rest of the requests to zoom behave as expected with no dns queries and all going through the http proxy.

 

to confirm, i have done the same test through windows/chrome/zoom webclient, and all requests occur as expected, with no dns queries and all going through the http proxy.

 

any ideas on what could be happening?
much appreciated.

thank you, storyhub.

the chart i reference to, there was no explicit mention to chromebooks or other OS, so i was unsure.

in your reply, you mention

> The chromebook is a unique device and was never designed to run Zoom directly in a browser.

i wonder if this is the official stance from Zoom.
i am representing a client, a school board to be specific, so they use chromebooks and have already directed them to use the app.
from my analysis of the tcp packets, this is a bug, but could not definitely say if its on chrome's side or zoom.

thanks again for helping out


Our Church uses low end chromebooks as well, but none of them are used for Zoom. They are used strictly for HTML 5 sites only with no streaming services. I have worked with several schools wanting to use chromebooks. But the OS does not do well for Zoom. That is why they had to develop interim software for the browser. For less than the price of many chromebooks you can purchase an Intel i7 mini computer that will do Zoom very well, plus will run OBS Studio and remote desktop at the same time. I just built 2 systems recently with $200 Lenovo mini PCs with i7, 16GB RAM, and Windows Pro 10 (Pro 11 is now available). So you could say the computer was free for the price of the OS. With the proper software installed the chromebooks MAY work for your client needs, but you also may find that time will be needed to make sure that those systems are maintained and properly connected to obtain a stable network. Chromebooks do have a history of not doing well with Zoom.

Based on the terminology you are using it is not clear exactly what software you are referencing.

The Zoom Web App is separate from the ChromeOS app and is intended to replace it, as support for ChromeOS apps are being phased out across all operating systems by until at least January 2025. We strongly recommend admins begin migrating users from the ChromeOS app to the new Zoom for Chrome Zoom Web App to ensure a smooth transition.

thank you for the reply.

would have been nice if you would have inquired what part of my terminology was unclear, for i am not a specialist in this system.

the problem arises when i try to join to a meeting using the link in the browser "Join from your browser".

let me know if this is what i call "web client", which is what i found to be the name in the zoom faqs, or what you call "ChromeOS app".
