[jira] [Reopened] (GUACAMOLE-1738) Docker Guacamole 1.5.0 Mysql Connection Error
[ https://issues.apache.org/jira/browse/GUACAMOLE-1738?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Mike Jumper reopened GUACAMOLE-1738:
------------------------------------
> Docker Guacamole 1.5.0 Mysql Connection Error
> ---------------------------------------------
>
> Key: GUACAMOLE-1738
> URL: https://issues.apache.org/jira/browse/GUACAMOLE-1738
> Project: Guacamole
> Issue Type: Bug
> Affects Versions: 1.5.0
> Reporter: Jonathan Kwan
> Priority: Minor
> Fix For: 1.5.1
>
>
> Ever since I upgraded my docker instance of Guacamole from 1.4.0 to 1.5.0, Guacamole is unable to connect to my mysql instance. Previously on 1.4.0 it was working flawlessly without issue.
>
> I've ensure the following are up to date at the moment:
> nginx - 1.22.1
> mysql - 8.0.32
> docker engine - 23.0.1 (i was previously on 20.x, and it was causing weird issues with the Java components in Docker to indicate "out of memory" which wasn't the case)
>
> Based on the error messages my hunch is it might be to do with
> guacamole-auth-jdbc-mysql-1.5.0.jar.
>
> Below is the error message from Guacamole:
