Teams not loading in Chrome or Edge
Hello!
Since a week ago my Teams stopped loading in Chrome or Edge, it only works in Firefox.
I have tried all the things I found in forums:
1. Chrome is up to date
2. Cookies are enabled
3. Cleared data
4. Opened in incognito, with no extensions
5. Resetted Chrome, installed again
Looking in DevTools, what I can see is that some cookies (it seems like authentication cookies) from the domain .teams.microsoft.com (with initial dot) are present only in Firefox.
Chrome only shows cookies from teams.microsoft.com and .microsoft.com.
Console from Chrome also shows error in POST api authz (error 411), which does not happen in Firefox and looks related to the cookie problem.
Last thing: web apps like Outlook, ToDo and Forms are loading ok. Those linked to onedrive (excel, onedrive, word, onenote) the page keeps loading, but does not shows error page or in console. Everything works in Firefox.
Appreciate any ideas.
Thanks!
Surya_Pammi, I've kinda solved it!
Another thread commented on vlan and firewall settings, filtering etc, and even though I don't have this at home, I thought what my PC and my wife's laptop have in common that is similar, since the network config wasn't the problem: antivirus!
So I just turned it off, tried to logon and Teams loaded!
Turned it on again and kept working, and could load again, no problem (probably because cookies are already saved/cached).
I still don't know exactly what is the issue. I've reset my PC a few times but didn't solve it, and Teams kept loading in Firefox. It doesn't seems like an AV block (logs/events doesn't show anything).
But in incognito, without the cached cookies, I still cannot load the page with AV turned on. 🤔
BTW, AV is Bitdefender free
Thanks again for the the discussion, it helped a lot!
We found a solution to the same issue. There are two desktop apps, Microsoft Teams Classic and Microsoft Teams (work or school).
Without Microsoft Teams Classic, Microsoft Teams (work or school) is not detected by Chrome. The key is to have both installed and linked to the same Microsoft account, so Microsoft Teams Classic is detected by Chrome and auto redirected to Microsoft Teams (work or school).
I hope this helps.
- It is great that some have found that disabling Bitdefender resolves the issue for them, but I do not have Bitdefender enabled on my machine. I happen to be using a Linux workstation and I am having the same problem, with not working solution.
- The problem also occurred on my machine where Bitdefender is installed. At least I can load Teams using Opera or Firefox.
- Ok, Just could you give a try by clearing all the third cookies and add these set of cookies recommend by Microsoft for Chrome.
[*.]microsoft.com
[*.]microsoftonline.com
[*.]teams.skype.com
[*.]teams.microsoft.com
[*.]sfbassets.com

Appreciate if you can share the error screenshotHi Surya_Pammi,
I've already tried these custom behaviors:
And cleared all site data:
But I have the same error, always:
This is the POST error that I don't get in FF, just in Chrome... I just don't know if it is the cause ou because the cookies from .teams domain are not set.
Hi dressito,
Do you have Teams desktop client installed on the machine that you are facing this issue? Please confirm if you are encountering same issue with Teams desktop client. If so we can once try clearing Local Teams Cache under %appdata%.
Also FYI, please revalidate browser versions of chrome (should be >= version 72)

- Hello dressito,
Could you please try checking if third party cookies are blocked in your Chrome browser?
Please check this in your browser...
1. Go to Settings and click on Privacy and security.
2. Then go to Cookies and other site data.
3. Enable Block third-party cookies in Incognito.
4. Under Sites that can always use cookies, add teams.microsoft.com
5. Clear cache in chrome, if required restart browser and try accessing TeamsThis fixed it for me. Previously, a reboot, restart of Chrome and even incognito mode did not resolve this issue.
I just added teams.microsoft.com under "Sites that can always use cookies" and checked "enable third party cookies"
I did not have to clear cache. It worked right away in a new tab.Hi Surya_Pammi, thanks for the reply!
I've tried to enable all cookies, block third party in incognito (my default) and to enable under sites, checking "enable third party cookies". I've tried many combinations like [*.]teams.microsoft.com, teams.microsoft.com, .teams.microsoft.com, and so on, and still not loads.
Even without site permission, cookies from teams.microsoft.com and .microsoft.com are loading/saved in Chrome, just from .teams domain that are not appearing in the list (DevTools > Aplication tab)These are from Firefox:
