Login demo Dynamics 365 F&O: AADSTS900561: The endpoint only accepts POST requests. Received a GET request

Question

Hi, I have deloyed Demo Dynamic 365 F&O by Hyper-V (VHD version) and I have configed LCS, Azure, Vitual Machine. But I log in to Dynamic Inv, it issue problem:

AADSTS900561: The endpoint only accepts POST requests. Received a GET request

I tried to fix by:

1. Which browser are you using? have you tried different browser to check if it works? Try opening a Private/Incognito window in your Browser (or clear the cache)
2. Have you tried adding the https://login.microsoftonline.com to your list of trusted sites?
3. Have you tried opening the Run Dialog and type inetcpl.cpl > Internet Options > Privacy tab > Under Settings > Sites > Per Site Privacy Actions > Enter the Login URL you are having issues (https://login.microsoftonline.com > Click Allow and OK

But all does not work.

Can anybody help me to resolve the problem?

Thanks so much
