I'm sorry to report that the issue wasn't fixed. It now seems to stall until a timeout occurs. This also happens when I try to setup the nokia app again:

To set a connection with Nokia Health you must have registered an application at https://account.health.nokia.com/partner/add_oauth2 .
Please enter the client id: *******
Please enter the consumer secret: *******
Please enter the callback url known by Nokia: https://localhost
Visit: https://account.health.nokia.com/oauth2_user/authorize2?response_type=code&client_id=*******&redirect_uri=https%3A%2F%2Flocalhost&scope=user.metrics&state=*******
and select your user and click "Allow this app".
Afterwards you will be redirected to your callback url with some additional parameters.
Example: https://your_original_callback?code=[code]&state=[state]
Please enter the full callback response url: https://localhost/?code=*******state=******* 

It stalls here for about 30 seconds, then fails:

I have this exact same issue on both my laptops at home. At work this issue doesn't occur. Neither does it on my VPS.

My conclusion for the moment: https://account.health.nokia.com is blocking my IP. Perhaps too many requests, refreshing of unexpired tokens. I don't know.

My findings summarized:

• Hang + MissingTokenError is very likely IP based
• Different machines on same home network experience this issue.
• It is not user based. Selecting a different user does not help
• Removing the application is you Nokia dashboard also does not help.
• The user-agent (python/request by default) has no influence.
• Trying another client (such as curl) does not help.
• Trying from another IP does help
• Issue only relates to account.health.nokia.com. api.health.nokia.com is not affected.
• Valid tokens can be used to do fetch and sync from the IP that hangs.
• This continues to work until expiry when another account.health.nokia.com request is require.

That said, I will continue to check on the issue. Hopefully it's just a temporary matter. Otherwise I will contact Nokia API team about it (I have been in contact with them before).

[jschram]

Interesting. I've tried to run it from some other IP's (office, ec2 instance and another VPS) but no luck... I'd say this rules out the blocking of my IP's, as I've now ran it through IP's I've never used before for this API.

Or, maybe we've managed to break their API 😉

[jschram]

Anyways, thanks for your efforts!

That's very odd, because on my VPS it's running smoothly now. The only thing I can think of is that I did try revoking the application a few times yesterday, so perhaps it's a combination of things. You can try revoking by clicking "Disconnection" here: https://account.health.nokia.com/partner/partner

[jschram]

Disconnecting didn't do the trick either, tried a few times, but no luck. Did run into this message though, so I suspect they might be updating or fixing their API right now:

You're right, the service is hanging for me now as well again. But I did happen to get through just now. I'm assuming it is on their end. Let's see how this plays out.

[magnific0]

I had contact with Nokia, they looked at an individual request I made. Turns out urllib3 hangs for a bit before sending the request by which time the authorization_code has expired (30 seconds after Allow this app). I found a simple solutions that speed the timeout up a bit. I was able to authorize the application more consistently now.

Be aware I made some changes to the setup flow:

• The application is able to start a HTTP server to listen for the callback and extract the authorization code so you don't have to copy it over. Notes:
  • Recommended local setup use a callback url with an unusual port that is available on your machine. I used http://localhost:8087.
  • Recommended LAN setup: http://192.168.1.123:8087. Where 192.168.1.123 is the LAN address of your server / device that runs nokia-weight-sync. Make sure your computer and device can talk to each other and the port you're using isn't firewalled on the device (8087) in this case.
  • Make sure you also change this callback url at Nokia Partners, click Edit my app to change.
  • If you want to use secure callback using https you need to set up a certificate.
• It is still possible to manually copy the value from the address bar. Simply reply "n" to the question "Spin up HTTP server to automate authorization?"
  • Be aware that you only need to copy the authorization code value from the callback url, not the entire url as previous. So https://your_original_callback?code=abcdef01234&state=XFZ, becomes: abcdef01234

Works, tnx! Also see #5

Nice! I'm closing this issue then. Thanks.

Hi, I still have this issue and none of the above worked for me. Also, now Nokia doesn't allow ip address or localhost as callback url and it must be on port 80 or 443.

Here is the error

@tolrahC I haven't tried changing my apps url in a while, but you are right that it has become more strict. Can you open a separate issue for this?

[tolrahC]

Just did #12
