@bubba198: The host UI also gives an error on the manifest. (The provided manifest file is invalid: Invalid OVF manifest entry: .)
@jan: After trying again several times, I always end up in the same error.
I have opened a case with VMware:
Status: Failed to deploy OVF package.
Start Time: Mar 5, 2018 10:56:34 AM
Completed Time: Mar 5, 2018 10:56:44 AM
The provided manifest file is invalid: Invalid OVF manifest entry: .
Additional Task Details:
VC Build: 7801515
Error Type: OvfImportFailed
Task Id: Task
Description Id: com.vmware.ovfs.ImportSession.Create
This happens with Graylog 2.4.3-1.ova.
I will give it a try with older versions and come back to you.
