Microsoft Teams Rooms

What you see	What it could mean (TLDR)	Recommended next steps
Devices Import Failed		Check the import file format and required fields Try importing a smaller batch If it keeps failing, share the error details and timestamp with your admin/support
Connection reset by peer - SSL_connect		This is usually a network/security issue - try again from a different network if possible Ask IT to allowlist the destination and ensure nothing is blocking secure connections
"error":"invalid_grant","error_description":"AADSTS50076: Due to a configuration change made by your administrator, or because you moved to a new location, you must use multi-factor authentication to access '	AADSTS50076 - MFA required	Your organization now requires MFA - you need to sign in again and complete MFA If this integration must run in the background, ask your admin about an “app-based” connection that doesn’t require MFA prompts
Graph Authentication Failed		Reconnect the Microsoft integration Ask your admin to confirm the app permissions/consent are still valid
"Issue: invalid_grant: AADSTS700082: The refresh token has expired due to inactivity. The token was issued on 2025-05-06T21:26:56.2488537Z and was inactive for 90.00:00:00.	AADSTS700082 - refresh token expired due to inactivity	Reconnect the Microsoft integration (sign in again) If it’s not used often, expect to reconnect occasionally when tokens expire
"Issue: Failed to open TCP connection to login.microsoftonline.com:443 (execution expired) Driver: mtr"	Failed to open TCP connection to login.microsoftonline.com:443 (timeout)	This is usually connectivity/firewall/proxy related - try again later If it persists, ask IT to allow access to Microsoft login endpoints
"Issue: invalid_grant: AADSTS9002313: Invalid request. Request is malformed or invalid.	AADSTS9002313 - invalid request malformed	Reconnect the integration (often fixes a broken/old session) If it still fails, your admin may need to reconfigure the integration settings (it’s sending an invalid sign-in request)
"Issue: temporarily_unavailable: Backup Auth Service attempted to serve request that previously failed at the Primary Auth Service, however the request also failed at Backup	temporarily_unavailable (50033)	Microsoft sign-in service is temporarily unavailable - try again in a few minutes If it keeps happening, reconnect later and share the timestamp with support/admin
"Issue: invalid_grant: AADSTS135010: UserPrincipal doesn't have the key ID configured.	AADSTS135010 - UserPrincipal doesn’t have the key ID configured	This usually requires an admin fix in Microsoft Entra/Azure settings Share the error + timestamp with your Microsoft admin and ask them to review the account/app configuration After they fix it, reconnect the integration
