This is a really simple problem to fix. But it’s irritating so I’m going to write a quick blog post about it.

You go to upload a file to a datastore in VSphere. The upload fails. You seean error message saying that there’s an untrusted certificate.

Control left click the link in the error to open the ESXI host in a new window and accept the untrusted certificate. It’s rather stupid in my opinion that the upload requires a direct connection on the client side to the host ESXI server and that this shows up as an error. But the fix is easy.

The way the error is presented is quite senseless as well though. There’s a read more link in the upload list. This presents a modal dialogue. Surely if you’re uploading something, it’s not unreasonable to have a status window shown for the duration of the upload where errors and other contextual information can be shown.

Overall, I like the VSphere web interface. I have been using VSphere for about 11 years now and the web UI is generally quite okay. But sometimes, the design decisions are a bit nuts in my opinion.
