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. Thanks
