Hi - I recently bought a Dell Iaptop and, when I try to join a Zoom meeting using the desktop client in Windows, I get the following message:
Unable to connect:
Check to make sure you're connected to a stable network that cannot be blocked by a firewall or proxy.
Error code: 5003
I can see from searching elsewhere that this error code is common with a range of possible resolutions, but none seem to work for me (restarting the computer, I have all the latest driver updates, status of Zoom servers is fine, reset Network Adapter settings, added Zoom as a trusted site). I have tried the obvious ones and only installed Zoom a couple of days ago so it must be the latest version.
What is particularly odd is that I have an older HP laptop on which the Zoom Windows desktop client works fine. This other laptop is on the same wi-fi network, both use Norton 360 and both are Windows 10 laptops. I was just wondering if this information might help to narrow down what the problem might be and if anyone has any ideas?
Thanks - yes both laptops are on the same network.
The Norton 360 software, which is installed on both laptops, controls the firewall. I tried temporarily disabling Norton’s firewall on the laptop with the issue but was still unable to join a Zoom meeting via the desktop client.
Can you attempt to connect to a Zoom meeting on the impacted laptop via a hardlined (ethernet) connection instead of Wifi?
You don't have any issues connecting to anything else on the new laptop correct?
After a little research, while those AV products DO control a firewall on your PC -> That firewall isn't the exact same thing as the system firewall. Example here -> If you cover one eye with both hands, then remove one hand... then you still are blocked.
Please attempt to connect to the meeting via a hardlined connection (this will answer a lot of networking variable questions) AND ALSO turn off both the AV and system firewall (I'm guessing there is a port blocked somewhere).
