Can not sign in for 365 products

[ketuhanh_dn]

Hello,

I am using 365 Excel. There is a notification in the header that "File name-Upload Blocked" and under the formula bar "SIGN IN REQUIRED We cant upload or download your changes because your cached credentials have expired"

I clicked to Sign in button, there is a pop up appears but not loading completely at all time. It pop up once more time when I close the file. How can I fix this? I tried to connect to another wifi to fix this but unsuccessfully.

Hi @ketuhanh_dn 

Please check the following 

1.  Your internet connectivity, this the main reason you might be getting disconnected from the OneDrive/SharePoint and the file is getting failed to upload

2. Try restarting your application 

3.  Repair your office.

@Faraz Shaikh  Thanks for your reply

1.  Your internet connectivity, this the main reason you might be getting disconnected from the OneDrive/SharePoint and the file is getting failed to upload

-> OneDrive still works when I can not see the sign in form. The internet is quiet good 

2. Try restarting your application 

-> I have done many times but unlucky

3.  Repair your office.

-> I reinstall by repair functions 2 times but it does not solve the problem
