Get ERROR Message: Unable to log into the network because the login credentials or the server certificate is incorrect after the

Zenworks Adaptive Agnet updated from 11.1 to 11.2 on some workstations.

We used Zenworks System Update to upgrade the agent from 11.1 to 11.2.Most of the machines updated successfully.But some of them failed, so we have to reinstall the agent manually.

The agent can be installed normally,but we can't login to zenworks anymore.Even if we unregisiter Management Zone and regisiter again.It always show "Unable to log into the network because the login credentials or the server certificate is incorrect".

Any Solutions?

Thanks.
