Describe the Bug

Per guidance under https://github.com/orgs/fosrl/discussions/1894#discussioncomment-15018258, I requested a license key from Pangolin's website and applied it to my self-hosted instance.

However, upon doing so, I'm now seeing the following error at the bottom of the login page:

When I check the license keys, it says they've been rechecked, and shows as not valid, but doesn't provide a reason why it isn't valid - it has a 10 year expiry, so what exactly is happening? Why was the license key allowed to be added if it was invalid from the beginning?

If I check the license key on pangolin.net, it shows as valid - judging by the last few characters, it appears to be the identical key, which would make sense as I copied/pasted it directly.

Deleting, and re-adding, the license key yields a "failed to fetch" error:

Pangolin is hosted on a VPS on RackNerd, so there shouldn't be restrictions on WAN access. If a specific firewall rule needs to be allowed, please let me know but I don't think I have anything restrictive setup as it stands today.

Environment

OS Type & Version: (e.g., Ubuntu 22.04): Ubuntu Server 24.04 LTS
Pangolin Version: Enterprise v1.12.2
Gerbil Version: N/A
Traefik Version:
Newt Version:
Olm Version: (if applicable)

(I'm not certain how to retrieve the above versions)

To Reproduce

Request a license key
Apply it to self hosted instance
Observe screenshotted error message

(I think these are the steps. It's not clear to me since I didn't start seeing the messages until a few days after applying the license to my server)

Expected Behavior

No error should be presented if the license key is valid, OR the license key should perform a check before applying, with a verbose error as to why it is invalid, and what steps the user should take to remediate it.
