Intermittent Timeout Issue with OIDC Authentication in Keycloak v25.0.6 : 'SocketTimeoutException: Read timed out'

,
1

Hi All,
We are currently using Keycloak version 25.0.6, and we are encountering an intermittent issue while authenticating with an OIDC identity provider.

Occasionally, we are getting the following error during login:

Failed to make identity provider oauth callback: java.net.SocketTimeoutException: Read timed out

Due to this, users are unable to log in to the application when the error occurs.

Note: This issue occurs sporadically and is not consistently reproducible.

We would appreciate it if you could let us know:

  • Whether there is a way to resolve this issue, and
  • If it is possible to increase the timeout duration for the identity provider authentication API call.

Your assistance in resolving this issue would be greatly appreciated.

That’s a timeout doing an HTTP call to the IdP. It’s not an issue with Keycloak, but with connecting to your provider. You can tweak the HTTP timeouts with the connections-http-client variables, defined here: All provider configuration - Keycloak

E.g. we were having some problems with read timeouts to high-latency endpoints, so we set KC_SPI_CONNECTIONS_HTTP_CLIENT_DEFAULT_SOCKET_TIMEOUT_MILLIS=30000
