Refresh_token request returns "Session not active"

I tried to send request:
POST …/realms/my-realm/protocol/openid-connect/token
Headers:
Content-Type: application/x-www-form-urlencoded
and 10 default headers from Postman
Body:
client_id: my-client-id
grant_type: refresh_token
refresh_token: eyJhbGc…

When I used KeycloakX version 14.0 I got correct result which included new access token.
When I used KeycloakX version 16.1 I got the failure: { “error”: “invalid_grant”, “error_description”: “Session not active” }

After I performed the request I saw my user session in active session list in keycloak administration console.

How I can fix that?
I would be grateful, thanks in advance.

We have also seen similar issues in our setup. The solution is not known yet. Any help from community will be appreciated.

+1 for me with keycloak 16.1 too.
