Zoom error code 5000: what it means and how to fix it

Short answer

Zoom error code 5000 means something between your device and Zoom's servers is blocking the connection, most often a VPN, antivirus or firewall, a proxy, or a network problem. Zoom has no fault on its side to fix. Check zoomstatus.com first. If everything shows Operational, turn off your VPN and antivirus, restart your router, and try again.

What this message means

Error code 5000 is one of Zoom's network connection errors (along with 5003 and 5004). According to Zoom, it means "an issue is preventing a connection between your device and Zoom's servers." Your Zoom account and the meeting link are usually fine. The Zoom app simply cannot open a connection to Zoom's servers over ports 443, 8801 and 8802. That happens when security software, a VPN, a firewall or proxy server, DNS, or your internet provider blocks or breaks the connection, or once in a while when Zoom itself has an outage.

Common causes

CauseHow to tell
VPN or other network-routing app is interferingThe error only appears while a VPN (NordVPN, company VPN, Cloudflare WARP, etc.) is connected, and Zoom signs in fine a few seconds after you disconnect it.
Antivirus or firewall is blocking ZoomWeb browsing works normally but the Zoom app alone shows 5000. The error often starts right after an antivirus update or a new security app install, and goes away when that protection is paused.
Corporate, school or public network blocks Zoom's servers or portsZoom works at home or on a phone hotspot but fails on office, campus, hotel or café Wi-Fi. Colleagues on the same network often see the same error.
Home router, DNS or internet connection problemOther sites load slowly or intermittently, or the error also appears on other devices on the same Wi-Fi. Switching to a mobile hotspot makes Zoom connect.
Zoom service outage or maintenancezoomstatus.com shows Degraded Performance or an active incident for Zoom Meetings, and many people report the same error at the same time.
Outdated or damaged Zoom installationThe error persists on every network, even a hotspot with VPN and antivirus off, while zoom.us opens fine in a browser.

How to fix it

1. Rule out a Zoom outage and a flaky connection

  1. Open zoomstatus.com and look at Zoom Meetings, Webinars, and Events. If it shows anything other than Operational, wait for Zoom to resolve it.
  2. Quit Zoom completely (Mac: zoom.us menu > Quit Zoom Workplace; Windows: right-click the Zoom icon in the system tray > Exit).
  3. Turn off your computer, unplug your modem and router, and wait at least 1 minute.
  4. Plug the modem and router back in, wait for the lights to settle, turn the computer on and open Zoom again.
  5. If it still fails, connect to a phone hotspot and try. If Zoom works there, the problem is your network (see the firewall fix below).

2. Turn off VPN and pause antivirus to test

  1. Disconnect any VPN or network tool (including Cloudflare WARP, iCloud Private Relay or a company VPN) and fully quit it.
  2. Temporarily pause your antivirus or internet security suite (Norton, McAfee, Avast, Bitdefender, ESET, etc.) from its tray or menu bar icon.
  3. Open Zoom and sign in or join the meeting again.
  4. If it connects, turn protection back on and add Zoom as an allowed or trusted app in that product instead of leaving it disabled.
  5. For a VPN you need, turn on split tunnelling and exclude Zoom, or ask your IT team to allow *.zoom.us through the VPN.

3. Allow Zoom through Windows Defender Firewall

Windows 10 and Windows 11

  1. Windows 11: open Settings > Privacy & security > Windows Security > Firewall & network protection. Windows 10: Settings > Update & Security > Windows Security > Firewall & network protection.
  2. Click Allow an app through firewall, then Change settings.
  3. Find Zoom (or Zoom Workplace) in the list and tick both Private and Public. If it is missing, click Allow another app and browse to Zoom.exe (usually in %APPDATA%\Zoom\bin).
  4. Click OK, restart Zoom and try again.

4. Flush DNS and try a public DNS server

  1. Windows: open Command Prompt and run ipconfig /flushdns.
  2. Mac: open Terminal and run sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder, then enter your password.
  3. To change DNS on Windows 11: Settings > Network & internet > Wi-Fi (or Ethernet) > Hardware properties > DNS server assignment > Edit, choose Manual, turn on IPv4 and enter 1.1.1.1 and 8.8.8.8.
  4. On Mac: System Settings > Network > your Wi-Fi or Ethernet > Details > DNS, click + and add 1.1.1.1 and 8.8.8.8, then click OK.
  5. Reopen Zoom and try again.

5. Uninstall and reinstall the latest Zoom

  1. Mac: open Zoom and choose zoom.us > Uninstall Zoom from the menu bar. Windows 11: Settings > Apps > Installed apps > Zoom Workplace > Uninstall (Windows 10: Settings > Apps > Apps & features).
  2. Restart the computer.
  3. Download the current installer from zoom.us/download and install it.
  4. Sign in again. If you need to join right now, use the Join from your browser link on the meeting page as a stopgap.

6. Have your network admin open Zoom's ports and domains

Work, school or other managed networks

  1. Send your IT team Zoom's article 'Zoom network firewall or proxy server settings'.
  2. Ask them to allow TCP 80 and 443 plus UDP 443 to *.zoom.us and *.zoom.com.
  3. For meetings and webinars they must also allow TCP 443, 8801 and 8802, and UDP 3478, 3479 and 8801 to 8810.
  4. If traffic goes through a proxy, ask them to exclude zoom.us and *.zoom.us from SSL inspection, since inspection breaks Zoom's certificate checks.

Still not fixed?

If Zoom still shows 5000 on a phone hotspot with VPN and antivirus off and a fresh install, try joining from the web client (zoom.us/join) or the Zoom mobile app to confirm your account works. Then ask your internet provider whether they block or throttle traffic to Zoom, since Zoom's own guidance lists that as a check. If you are on a managed work or school computer, your IT department controls the firewall, proxy and security software and is the right contact. Otherwise, open a ticket at support.zoom.com with the time of the error and your Zoom version (shown under Help > About Zoom).

Questions people ask

Is Zoom error 5000 my fault or Zoom's?

Usually it's local. Zoom describes it as something preventing your device from reaching its servers, typically a VPN, antivirus, firewall, proxy or network issue. Check zoomstatus.com to rule out an outage on Zoom's side.

What is the difference between Zoom error 5000, 5003 and 5004?

All three are connection errors meaning the app cannot reach Zoom's servers, and Zoom gives nearly the same fixes for each. For 5003, Zoom also recommends reinstalling the latest version of the app first.

Why does Zoom work on my phone but show 5000 on my computer?

Your phone is probably on mobile data or has no VPN or antivirus running, so nothing blocks it. Something on the computer or its network is blocking Zoom, most often a VPN, security software or a work network firewall.

Can I still join the meeting while error 5000 is showing?

Often yes. Open the meeting link in Chrome, Edge or Safari and click Join from your browser, or join from the Zoom mobile app on cellular data.

Does reinstalling Zoom fix error 5000?

Only if the installation is damaged or out of date. If the error comes from your network or security software, reinstalling won't change anything, so test with a hotspot and VPN off first.
