I got '400 : {"reason":"Invalid request : Redirect URI mismatch.","error":"invalid_grant"}' error after my ngrok re-started

API and Webhooks Authentication
1

API Endpoint(s) and/or Zoom API Event(s)
Oauth with Zoom

Description
Yesterday I succeeded getting access token, refresh token, and get information /me.
But today I re-started ngrok(free plan), so my domain is changed.
so I changed zoom app’s settings, and my code’s uri domain changed.
but after that, I always got the same error even I succeeded yester with this code.

{“reason”:“Invalid request : Redirect URI mismatch.”,“error”:“invalid_grant”}

I checked my server’s redirect code,
zoom market place’s settings,
all the redirect uri was same.

This is my local server’s redirect log.

Redirected to https://zoom.us/oauth/authorize?response_type=code&redirect_uri=https://e2a7-222-114-152-95.ngrok.io/oauth/zoom_callback&client_id=blabla

This is my app credentials.

Redirect URL for OAuth
Destination URL where Zoom will send the access token after the user completes the OAuth authentication.
https://e2a7-222-114-152-95.ngrok.io/oauth/zoom_callback

Add allow lists
https://e2a7-222-114-152-95.ngrok.io/oauth/zoom_callback

as you can see, all redirect uri is same.

What should I re-check for solving this error?

Error?
400 : {“reason”:“Invalid request : Redirect URI mismatch.”,“error”:“invalid_grant”}

Please let me know what should I check more.
Thanks.

I solved this issue by my self.
The problem was get access token api.
I sent different uri when I call get access token api after I redirected to my callback.
I’m going to next step.
