Sign In not working with Client Id and Screts

[Jaymin3893]

I was using this connector since last 4 months and all of the sudden signin is asking for password and even after providing that it is not working.
I tried with the fresh code and the steps which was mentioned here but still not working.

I am having the same issue.

My refreshes through the gateway have stopped working and Raiser's help desk said it's on my side... but all of my non RENXT connections are refreshing with no issue.
