Update Password E-Mail not Send to User

Helloes,

We use Keycloak (9.0) to manage our customer authentication. Our typical workflow consists of adding new users manually and then having them send an “Update Password” e-mail. This used to work in the past but now it stopped working completely.

From what I could gather so far:

  • Sending e-mails works in general, i.e. the “test e-mail” button works and sends an e-mail

  • The “Forgot Password” link works as well and enables the user to reset her/his password

  • execute-actions-email is triggered according to the logs, I see for instance the following in the server logs:

    2020-03-15 13:02:12,237 TRACE [org.keycloak.events] (default task-20)
      operationType=ACTION,
      realmId=master,
      clientId=b626e473-e584-469a-a18e-3a0439d3f01b,
      userId=<user uuid>,
      ipAddress=127.0.0.1,
      resourceType=USER,
      resourcePath=users/<user uuid>/execute-actions-email,
      requestUri=https://URL-TO-KEYCLOAK.com/auth/admin/realms/swarm64-customers/users/<user uuid>/execute-actions-email?lifespan=43200,
      cookies=[...]
    

I already enabled TRACE for logging, but no success. It seems, that the task to send the e-mail is never picked up.

Would be happy about any further debugging advice.

Thanks,
Sebastian
