Stupid guess, but can you also check the content of your guacamole/extensions directory? Some extensions (looking at you, TOTP) will make Tomcat crash with this exact error if multiple versions are loaded. CheersAntoine

You'll probably need to enable additional debugging in the Guacamole web application and try, again, and see if you get any more useful messages: https://guacamole.apache.org/doc/gug/configuring-guacamole.html#logging-within-the-web-application I don't know if this can help but here is my apache guacamole.conf file (/etc/httpd/conf/sites.d/guacamole.conf) I think the error you're seeing indicates it's more basic than this - this would be the Apache httpd configuration for the proxying Guacamole, but it seems like Tomcat is failing to load it for some reason. -Nick --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscr...@guacamole.apache.org For additional commands, e-mail: user-h...@guacamole.apache.org
