Exception when uploading OVA to vCenter when using Proxy

With the recent version vCenter 7.0.0b there seems still being an issue when having HTTP / HTTPS proxy configured and trying to import an OVA / OVF.
This is the error message you will see most likely:

Failed to deploy OVF package. ThrowableProxy.cause A general system error occurred: Transfer failed: Server not trusted: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target, note that HTTP/s proxy is configured for the transfer.

A quick workaround is to disable Proxy via VAMI and only enable it when you need id to download updates via Lifecycle Manager or for vCenter updates.

I have a support case open for this, let´s see if there will be a fix soon.

Update, there is a KB out at VMware that you need to specify NO_PROXY according to your environment to get this working again. 



  1. Thank you! My goggling about this eventually led to this post and this is exactly what I am facing too.

  2. Thank you! This resolved my issue too.

  3. Any update from the VMware case?

    1. Sadly it was closed by: "You are not using a supported proxy setup" as i use a proxy that is not pingable and thus have to configure it via /etc/sysconfig/proxy

    2. There is this KB out, and it´s all about setting the NO_PROXY right.
