Connection disconnected to OneDrive for Business

the connection to OneDrive Business was unexpectedly disconnected.
A reconnection is not possible - although it confirms that authentication is complete


The login in to a standard “OneDrive” is possible without any problems

Any idea ?
best regards

I am facing the same issue…please help


Sorry for the late response.

After setting the log level to VERBOSE, please reproduce the problem and send us the debug log file :

There is no credential information in the log files.

It seems to be a temporary problem with the OneDrive for business server.
If the problem persists, please contact us again.


problem still exists.
best regards

No support …what do I pay for ???

Sorry for the delay.

For the authentication problem we need to check the certificate problem first.

Please update local CA certificates to recent version. (125.9 KB)

Unzip the above file and replace the cacert.pem file in NetDrive with unzipped cacert.pem file.

cacert.pem is located at C:\Program Files (x86)\Bdrive\NetDrive3\cert .

After replacing the file you need to reboot your PC.

what about mac os

The same problem although the new certificate.
What possibility have I to get the refund of the purchase price.
The program is useless for me without using OneDrive for Business.
