Problem with custom identity provider oauth2

I create identity provider OIDC (private OAUTH2) and try login and I get 502 status from my keycloak
logs:

16:30:58,391 ERROR [org.keycloak.broker.oidc.AbstractOAuth2IdentityProvider] (default task-100) Failed to make identity provider oauth callback: org.keycloak.broker.provider.IdentityBrokerException: No access_token from server.
at org.keycloak.keycloak-services@11.0.2//org.keycloak.broker.oidc.OIDCIdentityProvider.verifyAccessToken(OIDCIdentityProvider.java:515)

Where you able to solve that issue ?
