Fangtooth trying to upload iso for VM

Just upgraded and I am trying to uoload an ISO to spin up a VM. I am getting

Http failure response for https://nas/_upload?auth_token=ryEQT2pNqmQwL3N8Oy3nENepWw-mFOdBlLM-4qUUN8L7j89SZBG88odk8q84NLYe: 413 OK

Not much to go on for troubleshooting but that is all I see. I was able to upload one ISO but not another one.

Thanks for any help

Looks like 413 means it’s too big? It is bigger than the other ISO I uploaded. Anyway around this?

Looks like it was NGINX reverse proxy, I saw a post that mentioned it. Browsed to the IP and it works. Will have to investigate that.
