Proxy error: UnprocessableEntity, Failed to get installation and oauth information for app

Hi, 

We are having same issues with an app being developed for one of our customers. 

If I bypass the secure setting/proxy and manually enter an access token for the app then the requests go through and we get data.

However, when we try to go via the secure proxy we get the same error with 

{:code=>\"UnprocessableEntity\", :status=>\"422\", :title=>\"Unprocessable Entity\", :message=>\"Failed to get installation and oauth information for app.\"}

In the app settings we have successfully logged in and it is showing a green check marker next to the Oauth login.

Everything in manifest.json also looks correct

"parameters": [
    {
      "name": "baseUrl",
      "type": "text",
      "secure": false,
      "required": true
    },
    {
      "name": "token",
      "type": "oauth"
    }
  ],
  "oauth": {
    "client_id": "Z****",
    "client_secret": "5*****",
    "authorize_uri": "https://***/identity/connect/authorize",
    "access_token_uri": "https://***/identity/connect/token",
    "scope": "***"
  },

And when checking Network in the browsers Developer Tools I can see that it is correctly including Bearer {{setting.token}} for Authorization.

Would appreciate some assistance in checking logs as I can't really see anything wrong in the app itself for this.

That was it, dont know how i missed that, thank you 

I was able to authenticate upon initial load/install of the app but I don't have any way to see logs when it goes for refresh token.
This worked successfully 5 hours ago. and when i came back to it I am getting this error. so I am assuming the refresh token failed, the expires_in key is in the response from the token endpoint.
