Got the error "Throwable proxy"?

I had the issue when I was trying to deploy a OVF template and I got the error throwable proxy as shown in the picture below

In my case, the issue was related to DNS. Here are a couple of solutions you can try:

• Log in to vCenter using its IP address instead of the hostname.

• Try logging directly into the ESXi host using its IP address.

These steps served as a workaround for my issue.
