As your post needs moving to the area for ESXi, I have reported it to the volunteer moderators.
I was trying to access a trial for vsphere 8. I have been waiting patiently for 35 days. It tells me I have 25 days left on my trial, but when you hit download, all it says is "Unable to process your request. Please try again later." 35 days of this.
This has been going on for months apparently for a lot of people. The argument that it's "due to demand" is a bit comical. VMware can't figure out a way to provide a key and dl link for a trial inside of a few minutes? Apparently...
I am having the exact same issue but with ESXI 8. I have a key but I am unable to download the ISO.
"Unable to process your request. Please try again later."
