Hello,
I have keycloak inside a docker container and a microservice architecture, in which I have a gateway with multiple endpoints. In those endpoints I use a middleware in which I made a request to "/auth/realms/testrealm/protocol/openid-connect/userinfo" so if the token is valid this endpoint give me a 200 and the request follow to the services, if is not valid the gateway return a 401.

So if I ask for a token directly to the keycloak container in "/auth/realms/testrealm/protocol/openid-connect/token" everything go fine and works.
Now I create an endpoint to ask for a token through the gateway, I have a response with the token but when I use it in an endpoint I receive :
"{"error":"invalid_token","error_description":"Token verification failed"}"

The only different in the token that I can see is :

JWT token receive directly from the container

"iss": "http://localhost:8080/auth/realms/testrealm"


JWT token receive directly from the container

"iss": "http://localhost:5001/auth/realms/testrealm"


8080 is the keycloak service and 5001 gateway.

What can I do to make it work? I created the /auth/realms/testrealm endpoint just in case, but is not call.
