Hi all.

We unexpectedly encountered the following error while trying to upload files via web vSphere Client to our datastores connected to vCenter 6.7:

"The operation failed for an undetermined reason. Typically this problem occurs due to certificates that the browser does not trust..."

The solutions described in the article "The operation failed for an undetermined reason" transferring files through vSphere Client (2147256... haven't helped us.

Also while we're trying to connect to our vCenter via VMware workstation we got the list of VMs but can't connect to the each of them: got error "Adress unresolved".

We don't know what past activities could be a reason for such changes, because it worked earlier.

Any ideas?
