    [ https://issues.apache.org/jira/browse/GUACAMOLE-919?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17010865#comment-17010865 ] 

Mike Jumper commented on GUACAMOLE-919:
---------------------------------------

Is there a roughly consistent period of time between each first occurrence of the error and the most recent successful auth attempt that precedes it?

Are there any other errors in the logs at the time that authentication fails?

> Hi,
> we use guacamole with postgresql and openid extension. Guacamole and guacd is deployed inside a k8s cluster.
> For some reason, the authentication doesn't succeed sporadically; there is only a blank page and this error message in the guacamole log:
> *[pool-1-thread-1] WARN o.a.i.d.pooled.PooledDataSource - Execution of ping query 'SELECT 1' failed: An I/O error occurred while sending to the backend.*
> I suspect there is a weird timeout happening between guacamole and postgresql but could figure out why.
> Any hints are much appreciated. Thanks
