'Connect With Enode' button not working

Pressing the Connect With Enode button in the app or on desktop doesn’t do anything.

I checked the Chrome Dev Tools on desktop and saw that the button creates a POST request to a get_tlm_oauth_uri endpoint, and every time I click the button it gets back a response with a body of {"status": "error"}. I was able to reproduce this using curl:

curl -i -X POST https://api.iternio.com/1/vehicles/get_tlm_oauth_uri -H 'accept: application/json, text/plain, /' -H 'accept-encoding: gzip, deflate, br, zstd' -H 'accept-language: en-US,en;q=0.9' -H 'authorization: APIKEY [REDACTED]' -H 'content-length: 277' -H 'content-type: application/json' -H 'dnt: 1' -H 'origin: https://abetterrouteplanner.com' -H 'priority: u=1, i' -H 'referer: https://abetterrouteplanner.com/' -H 'sec-ch-ua: "Not(A:Brand";v="8", "Chromium";v="144", "Google Chrome";v="144"' -H 'sec-ch-ua-mobile: ?0' -H 'sec-ch-ua-platform: "Windows"' -H 'sec-fetch-dest: empty' -H 'sec-fetch-mode: cors' -H 'sec-fetch-site: cross-site' -H 'user-agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/144.0.0.0 Safari/537.36' --data '{"typecode":"hyundai:ioniq5n:25:84:awd","tlm_type":"enode","redirect_uri":"https://abetterrouteplanner.com/index.html?state=abrp-enode-web-tlm-ib3v7oq&code=void","vehicle_id":[REDACTED],"manufacturer":"Unknown","session_id":"[REDACTED]"}'

I’ve tried pressing the button while on mobile data and ensured no ad blocker extensions were enabled on web, I even disabled my DNS filtering but none of these helped.

Any ideas on how to get around this? I understand the connection with Hyundai vehicles isn’t great but I purchased a premium membership specifically for this feature and it’s very disappointing to see that it doesn’t work.

Let me know if there are any more details I can provide.
