Troubleshooting seemingly disjointed problems and crowdsourcing recommendations is always a tricky thing for us to navigate. Personally, I like to look at things like "absolutely everything is okay except for one single app" with a grain of salt unless I can back it up with empirical evidence

I am seeing in another channel talk about Zoom pushing Macbook CPU to almost 100% especially when other apps are open, and the effect is worse per model and HW specs. I don’t know this to be true, but a couple of respectable folks saying so. If so, one takeaway would be to make sure Zoom client

The only problem I have there- with “where your vendor tells you to start”- is that the vendor loves to push “go to latest code”. THEN… Oops- now you got a new problem. Better downgrade. Let’s try this escalation code. Whoopsie, new bug… Let’s try THIS escalation code. Darn… different bugs.

We had a huge upswell of Mac users not being able to connect and the newest OS was at fault. Older macs further away...no issues. Mac's with new OS right under an AP... couldnt connect reliably, huge CPU spikes and or crappy wifi. Ahh, I love Apple. But yeah, in this instance, dont discount

I was just following this thread along until a ticket dropped in my lap this morning with a large Zoom session that apparently was cratering all over the place. After reviewing the connection report from Zoom for the session in question, there’s a pretty strong correlation between clients

We are an Aruba shop at Denison University and have received reports of issues on Zoom and Google Meet as well mostly on Mac OS. Looking into the Zoom dashboard statistics of some of these calls we are seeing the "Max Loss" percentage go up to 99% frequently and back down to 2-6 % on wireless when

Ok, I’m going to throw something out there that may sound stupid, but I am ok with appearing stupid. When a client initiates a zoom call is that done via UDP or TCP? If it is done via UDP, can the session fail over to using TCP SSL connectivity in the middle of the call? Can that in turn create

Making sure you have the UDP ports permitted for Zoom is important to ensure quality. Whilst Zoom will work with just TCP 80 and 443 enabled, clients that are restricted to using those ports will more frequently run into quality issues, and from our experience will more frequently be forced to

Zoom starts out trying UDP/8801, then if that fails goes to TCP/8801. Then if that fails it runs SSL on TCP/443. Then if that fails the user has to use the web client over http/https. You can find the networks needed in an automatically updated text list format for linking to dynamic

These are all outbound 8801 connections? We don't block outbound, but we do block inbound, and our firewall is blocking a number on port 8801. Zoom's Firewall article https://support.zoom.us/hc/en-us/articles/201362683 only shows outbound as being required, but the inbound traffic is puzzling.

Are the blocks that you’re seeing coming from one of the Zoom subnets in the listing? https://support.zoom.us/hc/en-us/articles/201362683-Network-firewall-or-proxy-server-settings-for-Zoom speicifies that all the subnets should be allowed both inbound and outbound. It might not all be
