Douglas Heriot commented on GUACAMOLE-919: ------------------------------------------ Sorry I've not looked at this for a while. I've just rebased my changes over the current master since the 1.2.0 release, and addressed the issues raised in the pull request review: [https://github.com/apache/guacamole-client/pull/488] I've also added a pull request that adds documentation for these new properties: [https://github.com/apache/guacamole-manual/pull/146] > An I/O error occurred while sending to the backend > -------------------------------------------------- > > Key: GUACAMOLE-919 > URL: https://issues.apache.org/jira/browse/GUACAMOLE-919 > Project: Guacamole > Issue Type: Bug > Components: guacamole-auth-jdbc-postgresql > Affects Versions: 1.0.0 > Reporter: Mechanix > Assignee: Nick Couchman > Priority: Minor > Attachments: image-2020-01-27-15-19-26-634.png > > > 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 couldn't figure out why. > Any hints are much appreciated.
