Mechanix commented on GUACAMOLE-919: ------------------------------------ [~mjumper] thanks for confirmation [~vnick]I think you´re right with this approach. The original postgres jdbc driver has a lot of options regarding to connection timeouts ([https://jdbc.postgresql.org/documentation/head/connect.html#connection-parameters). |https://jdbc.postgresql.org/documentation/head/connect.html#connection-parameters)] specially *connectTimeout* and *socketTimeout* I guess it would help if we could pass those parameters in guacamole.properties. If you have questions about my setup, please reach out to me. > 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.
