Question

I'm receiving a blank page when trying to Sign in to Account during Entra Connect Sync upgrade/install. I've tried to do the Ctrl+/- but that doesn't work.

I have tried (re/un)installing the connect sync app but can't get pas the blank Sign in screen.

Hello @Don Mason,

Thank you for posting your query on Microsoft Q&A.

Based on your description, it seems you are encountering a blank login screen when modifying Azure AD Connect settings or during installation. To ensure we're aligned, I've attached a screenshot for clarification.

Unfortunately, there isn't a direct solution for this issue; it requires investigating several factors to determine the root cause. Additionally, this doesn't seem to be strictly related to an Entra Connect sync issue.

Here are a few steps you can try:

1. Can you log in to portal.azure.com using Edge on that server? If yes, also try logging in to login.microsoftonline.com from Edge.
2. If the logins work on Edge, make sure to set it as the default browser on the server.
3. Change the IE Enhanced Security settings to “No.”
4. Ensure TLS 1.2 is enabled on the server. You can refer to this documentation for a PowerShell script to verify TLS 1.2 settings.
5. Is per-user MFA enabled for the account? If so, temporarily disable MFA and check if the issue persists.
6. If disabling MFA resolves the issue, make sure to add the required URL for MFA to the trusted sites list: https://secure.aadcdn.microsoftonline-p.com
7. Open inetcpl.cpl, navigate to the Security tab, and adjust the security level settings to “Low.” Then, test again.

If the issue isn't resolved after any of these steps, please Let me know how it goes.

Found this info on another link...

What's helped me in the past is doing a full IESettings reset.

 RunDll32.exe InetCpl.cpl,ResetIEtoDefaults   

From an Admin console prompt, click the button and then 'yes'. You might need to reboot, but I think after 20 seconds or so, you should be able to re-verify your account.

Just tried it, and it worked a treat :-)

Thanks for the help. I ended up fully uninstalling and following a guide that our new MSP provided which got it re-established. After we switched over to them, I no longer need the sync to happen.
