title: Is possible to decline all old access tokens?
body: <p>I am developing an android mobile client and signing with oauth2 to our server that is written in c#. Everything is working well, until the server is rebooting.</p>
  
  <p>I'm crashing every call to the server.. at first I've thought that my access token is not valid anymore. but after I've decided to have my own local server I saw that my calls do reach the server and they crash inside because of some static lists of tokens and user data that the server team developed and obviously getting cleared after restarting the server.</p>
  
  <p>I've told them to recreate their lists of data and access tokens, but no luck for me there.. </p>
  
  <p>My question, 
  I'm not so good in server-side and oauth2 developing but i'm pretty sure there is a solution for what i want. I've tried searching for few hours without success. My thought is - To make the server decline all old access tokens from previous run of the server - and i will get unauthorised code in my client (Now i'm getting just crush in server that i don't know why and how to react in my app) Something like - Each time the server restart it will have a random seed and will create its access tokens with this seed.</p>
  
  <p>Is there something like this ? or some other "Not so much work" solution for the lazy server-side team :)? </p>
