[jira] [Commented] (GUACAMOLE-972) RDP file upload fails with HTTPS on for Tomcat

["Mike Jumper (Jira)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/GUACAMOLE-972?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17047912#comment-17047912 ] 

Mike Jumper commented on GUACAMOLE-972:
---------------------------------------

I have HTTPS enabled on a Tomcat that is directly exposed with no reverse proxies in between. File uploads on RDP fail with an "internal error" appearing on the client almost immediately after starting. Looking at browser DevTools is not yielding any clues as to why - there's only a net::ERR_CONNECTION_RESET. The request appears to be correctly formatted and uses HTTPS and the correct port.

My guess would be that:

* This is not a bug in Guacamole, nor an issue specific to 1.1.0.
* The relevant connector in the Tomcat settings is configured with a maximum request body size which is effectively blocking your upload attempt.

I'd recommend checking the connector and its settings (including defaults). If things still don't work, please post to the user@guacamole.apache.org mailing list rather than open a new issue here. Something which works with HTTP but not HTTPS is unlikely to be a bug in Guacamole, nor is it likely that Guacamole has a bug which prevents its use over HTTPS (this would have been tested prior to release and is how Guacamole is used in production).

Posting this here even though I can't pinpoint the exact cause yet so that this makes it into 1.2.0 if need be...

Scope of 1.2.0 has already been set.

> This used to work previously in 1.0.0 albeit I can't directly compare since up until now I've been using Fedora and the distro-provided Tomcat and now I'm testing with CentOS 8 + Apache upstream Tomcat with EPEL 8 tomcat-native. The server/tomcat configurations however are identical.
