zoom meetings issue

Are you certain that you have all the Zoom related ports open.  I have no exclusions or exemptions and Zoom works fine for me.  Here is the port list that I have setup in services which I took from the Zoom website:

Hi,

there is something wrong with that list, smtp, ftp, ssh seems wrong to me. Try this website for accurate ports

Hi All,

Thanks for your replies! I'll quadruple check the ports and everything again. I may have missed something. I'll post back after Ive checked .

Thanks again!

Hi, Ive checked my ports and Ive added 1 port on the list you gave me but its still not working.

Just taking a step back about this problem.....I cant get to any sub domain *.zoom.us webpages.

https://explore.zoom.us/meetings - times out

https://zoom.us/signin  - works

Download Center - Zoom works

https://support.zoom.us/  - times out

https://zoom.us/pricing  works 

Have I done the syntax wrong? Its just the zoom sites!

Hi,

I would suggest you need to check your logviewer and then your ISP. I can click on one of those websites and are connected straight through. I do not have any zoom exception in my WEB setup.

All of those ports you have are an overkill and not required and none of them a shown in the zoom support site.

HI Ian,

Thanks again for replying so quickly!

I think i may have figured it out! Think i just needed some sleep! It was nothing to do with the Sophos firewall. One of my colleagues (someone anyway) decided to add the *.zoom.us in internet options to by pass the proxy.

That explains when I look in the logs I dont see anything!

I manually removed it on a PC i was testing on and it is working on it. Im now changing the GPO so hopefully this works.

So sorry to involve everyone here and it wasnt even a Sophos XG issue!!!

Yea i think youre right with being overkill, i'll start removing those ports Ive got to its more clean!

Thanks again everyone! Really appreciate yours and everyones help!
