<p>A (private) program I use which accesses the OSM API has stopped working since the last time I used it, a couple of weeks ago. Read-only calls to the API, including a (proven correct) Authentication header are now failing with 401 Unauthorized, with the returned body indicating a problem with the username/password. The same call without the Authorization header succeeds. I swear nothing has changed on my side; double-checking the auth header with Fiddler shows the username/password I expect, and I can still logout/login using these values (which I haven't changed).</p>
<p>Is there anything going on, or has anything changed on the API, that may be causing this?</p>
<p>Sample URL: GET on <a href="https://api.openstreetmap.org/api/0.6/relation/8465619">https://api.openstreetmap.org/api/0.6/relation/8465619</a></p>
<p>I know I can just remove the authentication - it was added for "future use" anyway - but why has it suddenly broken?</p>
<p>Thanks,</p>
<p>Colin</p>
