Hi Guys,  
I’m trying to add Paytm OAuth to my Discourse forum using the discourse-oauth2-basic plugin, but I’m having trouble getting it to work. I followed the instructions in the plugin’s readme file, but when I try to log in with Paytm, I get an error message saying “Authorization timed out, or you have switched browsers. Please try again.”  
I’m not sure why it isn’t working.

Any help would be greatly appreciated!

Below is the error I found in discourse log:

```plaintext
