This made my head explode. We're teachers, not IT technicians. Can you give a level-appropriate how-to for us, who get the "error/Error while requesting an oauth token" error?
I have no idea to whom you are talking to, since https://moodle.org/mod/forum/discuss.php?d=226773 is a thread which I created almost two years ago, I'll take a shot.
> This made my head explode.
What is this _this_? If you meant https://tracker.moodle.org/browse/MDL-39203, it is closed now. I hope you could reconstruct your head from the mess that explosion created.

Sorry. By definition, somebody who maintains a web service on an Internet server is an "IT technician".

In general, the same error messsage can pop up due to different reasons. Think of an error message as a symptom, not the cause. The process of diagnosing is called "debugging" amoung IT technicians. On moodle it manifests to https://docs.moodle.org/en/Debugging.
Edit. Noticed the explosion spreading: https://moodle.org/mod/forum/discuss.php?d=329782. (Read "Forums code of conduct" https://moodle.org/mod/forum/discuss.php?d=329782 > "Post your question in one forum only".)
HI David - just to let you know I deleted your duplicate post and to make it easier for people to find your question and help you with this, I split your recent reply (and Visvanath's response) to make a new thread which should be more visible. I hope you get this sorted soon. (And I'm a teacher, not an IT technician too )
David, Can you tell us what version of Moodle you are using as this seems to have been fixed on more recent versions - unless it is broken again (unfortunately 3rd parties do sometimes change their API which affects those trying to link to them, such as Moodle)
