How to add OAuth2 protocol in ADFS

Question

I tried to get token from ADFS server in postman.

POST https://{adfs-domain}/adfs/oauth2/token

This is the response:

Error Detail: MSIS7065 :there are no registered protocol handlers on path /adfs/oauth2/token

And also, in authorize request case is same return error:

I am checking configuration by request that

https://{adfs-domain}/adfs/well-known/openid-configuration.

In Json data:

• issuer value (https://{adfs-domai}/adfs) url page show 503 error
• authorization_endpoint, token_endpoint show same error MSIS7065
• jwks_uri may be is working, return key [ { kty, use, alg and so on } ]

Json response:

}

The returned values are the same as in the JSON above, and it appears that items like "password" are supported under the grant_types_supported field. However, I am curious about the reason for the MSIS7065 error. Can anyone provide more information?
