Austin, The problem _may_ be to do with the RealVNC auth you have set. I'm unable to help with specific macOS questions, however - as Nick has commented recently - RealVNC does have mechanisms that 'standard' VNC does not. This series of posts may be of some use in explaining that: https://l

Takuya, Mike's rule of thumb has been 1 core and 2GB memory for ~25 users. You seem to have followed that well, although I don't recall if Mike differentiated with regard to where the memory was allocated (I see you have specific settings for Tomcat). I've never had need, nor tried, the numb

Fernando, I have zero experience of your remote environment, however perhaps you could try initially connecting direct with Remmina/FreeRDP (pref the same version as you're using for Guacamole)? If that works then try Guacamole again, specifically disabling all the caching options. It may

Timo, If I understand your system correctly I suggest you're missing out on the full benefits of Guacamole. My experience of VNC direct (which is what I take you to be doing) is that it can be quite slow, especially with limited bandwidth. Given the same bandwidth capacity I have found Guaca

Thanks for the information. I'm no expert on M$ licensing, it seems somewhat of a black art, but I don't see why you'd need additional licenses. As far as Windows is concerned Guacamole just connects via standard RDP on (usually) 3389. Unfortunately I'm not in a position to replicate your sit

Hanadi, It would be useful to tell us what the message actually says first. A 'blue screen' does sound like a Windows issue, the content of the message is likely to assist in determining that. In addition to that the Guacamole log files will be useful, from around the disconnection time - ca

Just to followup Mike's comments with an 'real world' example. For some years I've supported an installation that has had upwards of 100 concurrent users. This was done via a single VM with 4 cores allocated and (I think) 12GB RAM, there was no proxy server involved. There have been essential
