Start with the simplest. Most users resolve it by step 3! 👍

1. 1️⃣ Clear Cache and Cookies
   The #1 fix! Go to Chrome browser → Three dots → More tools → Clear browsing data. Select "Cookies and other site data" + "Cached images and files" (All time). Hit Clear data. Restart Teams and try logging in. Boom—fixed for 80% of cases!
2. 2️⃣ Update Chrome OS and Teams App
   Outdated software? No more! Click time icon (bottom right) → Gear → About Chrome OS → Check for updates. For Teams: Open Chrome Web Store, search "Microsoft Teams", and update. Relaunch. Pro tip: Enable auto-updates in Settings → Apps.
3. 3️⃣ Disable Extensions and Incognito Mode Test
   pesky extensions blocking? chrome://extensions/ → Toggle off all. Test Teams login in Incognito (Ctrl+Shift+N). If it works, re-enable one-by-one to find the culprit (ad blockers are common villains).
4. 4️⃣ Reset Network and Check VPN
   Network woes? Settings → Network → Reset Wi-Fi/mobile. Disable VPN/proxy temporarily. Test on mobile hotspot. Ensure no corporate firewall blocks teams.microsoft.com.
5. 5️⃣ Reinstall or Refresh Teams PWA
   Install fresh: Chrome Web Store → "Microsoft Teams" → Add to Chrome. Or right-click Teams icon → Apps → Uninstall → Reinstall. For PWA: teams.microsoft.com → Menu → Install Microsoft Teams.
6. 6️⃣ Advanced: Powerwash (Last Resort)
