One computer in my home home network can't connect to zoom

[funkfly]

There are plenty of devices in my home network - tablets, laptops, smartphones - all of them are able to connect to zoom without a problem. As expected.

But I have one device, and old iMac, that can't connect to zoom.us. The issue is with the zoom app, and with every browser I'm trying. The browser shows a timeout error.
I've tried to look of there's a firewall, a faulty hosts file on the computer, or even an issue with the router, but couldn't find anything.

I've tried uninstalling the zoom app, using the uninstall procedure, but that didn't help either.

I can't find any similar issues online.

I'm kinda lost for solutions here.

Can someone help me please?

Hi @funkfly! What software system is your iMac running on?

Hi @Bri -

It's 10.13.6 - High Sierra

I've stored this for numerous months no longer understanding what it changed into. I had some creative ideas to work with tablesaw, but none labored.

I thought I'd update here that I solved the problem by using a VPN.
When I turn it on that particular device, the problem goes away.
