token_rejected **on PUT only** - previously working app

I have an app that has been working for two-way contacts' sync for quite sometime. Nothing has changed on my end.

Now, any PUT request is getting a 401 "token_rejected" error while all the GET requests continue to work fine. Both are using HTTPS.

Any ideas on what the problem may be?

I double checked, and my contact permissions are read/write, and I tried requesting a new key & secret.

  • If I switch to using a Authorization header it gives: unable_to_determine_oauth_type

    But otherwise it works identically. GETs work perfectly, PUTs all fail. This app has been up and running for about 2 years without issue.
