Error Code 5003

[lovefaithhope]

I have not been able to join Zoom Meetings for 2 weeks.  I'm getting "Unable to Connect: Check to make sure you are connected to a stable network that is not blocked by a firewall or proxy."  Error Code 5003.  I've tried a number of proposed solutions including uninstall/re-install Zoom.  Can anyone help?

Hi @lovefaithhope , thank you for posting for the first time to the Zoom Community!

I'm sorry to hear that you're experiencing issues with error code 5003. Do you currently have VPN enabled?

Keep me updated!

hi @CarlaA 

I'm also facing the same issue; I'm not using a VPN but always get an error while opening the Mac OS app. However, if I open the browser, it's working; moreover, I also disabled my firewall. I just tried to reinstall my Zoom using the last version but still encountered the same issue.

Hi @aldinokemal thank you for posting for the first time in the Zoom Community!

Can you please uninstall the application by following steps outlined here: https://support.zoom.com/hc/en/article?id=zm_kb&sysparm_article=KB0065146#collapseMac . After you have uninstalled, please reboot your Mac, then go ahead and reinstall the application. Once you have done that, please try again and let me know how it goes!

I still encounter the same issue; I can't do anything with the Zoom app, login, or check updates.
All fails. I have made sure my VPN is disabled.

Thank you @aldinokemal for the updatel. 

In this case, please try to download this previous version here: https://zoom.us/client/5.17.11.31580/zoomusInstallerFull.pkg

If possible, I would also encourage you to reach out to your network administrator to check the firewall and proxy settings.

Keep me updated!
