When uploading file to Datastore you receive: The operation failed for an undetermined reason. Typically this problem occurs due to certificates that the browser does not trust….
In most corporate environments you will be using an Internal or External Certificate Authority and so you will be looking to use that, however in my lab I haven’t set one up.
When you connect to your vCenter (I have tested with Chrome and IE) you receive: There is a problem with this websites security certificate
Select Continue to this Website (not recommended)
Your vCenter page will load. At the Bottom Right there is an option to Download trusted root CA certificates
NOTE: I only saw and tested this with vSphere 6.5 and with the VCSA – I have read this option is only available with VCSA and in 6+
Select this and save the ZIP file
Open the file and navigate to the Certs folder – there will be a Linux, Mac and Windows folder – open the appropriate folder
There are two files, we want the file ending in 0 (NOT r0)
Extract this file by dragging to an appropriate directory
Rename the file by changing the extension from .0 to .cer
Open a Command Prompt with Administrator rights and select Yes at the Prompt
Type: certmgr.msc
And press Enter – this will bring up the Certificate Manager
Navigate to Trusted Root Certification Authorities and expand this
Right click on Certificates and select All Tasks > Import
Select Next and Browse to the Certificate you just renamed and select Next
Leave the Defaults and Finish
Select Yes at the Security Warning
And you should see: Import Successful
Close your Browser and then Re-open and try to access vCenter again
After this I was able to upload files to my datastores
Thank you so much
