Trouble setting up application with Withings

[jacket18]

Trying to register an application with Withings, I keep getting "Internal Error. Please try again." I looked at the Withings API documentation and found the following:

https://developer.withings.com/oauth2/#tag/glossary

Your URL must :

starts with https
be a valid URL, provided as a URL-encoded string. Please refer to w3schools URL encoding reference to learn more about URL encoding.
not be greater than 255 characters.
neither contain an IP or 'localhost'. Only port 80 and 443 are allowed.

That seems to contradict your setup steps. Do you know of a workaround or do you by chance have an update (or suggestion) to get this to work with this (presumably) new policy.

Either way, thanks for creating this. Hopefully I'll be able to use it!

It looks like Withings is only accepting https / port 443 callback URLs now.
