Hi all, I'm struggling to create an OAuth2 Client working. It's the first time I create one, so please bear with me while I explain all the steps I have taken. I'm using Ignition 8.1.37. **How can I get this working??** Thank you in advance. I have the client created in ignition. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/c/f/cf343e653aa20158056b87182d972a8618497d86.png) I have configured the email OAuth2 Profile for gmail. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/9/c/9cc53249bbf6262cd1e4cba8d7fa7c9938e4d3bb.png) The First issue I encounter is that the access token seems to be invalid. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/9/9/99627d50801b402470bc87eff5b0490ba73d6e8d.png) I have tested the authorization and it seems to be ok. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/0/4/04087be89b5e910c4720b9b13314cdd0fe65ecab.png) I then test the token, and that is also working. ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/f/9/f938ddd053546bdd3f9742950bd31b6331ce0851.png)

First, please edit your post and fix the formatting of the exception traceback: Please see [Wiki - how to post code on this forum](https://forum.inductiveautomation.com/t/wiki-how-to-post-code-on-this-forum/77831). Second, buried in that traceback is a connection timeout error. You have a network problem, not yet an auth problem. Find out why the target is dropping/ignoring the request.
