Hello Mike thanks for your reply, In the meanwhile I’ve narrowed down the cause somewhat.
An experiment yesterday from a private Win10 Client within the same vlan as the Guacamole installation showed Guacamole RDP with Swissgerman keyboard to work flawlessly. Suspecting my NGINX Proxy also turned out to be baseless as rerouting my local client to include NGINX still worked fine. I’ve been able to narrow the cause down to be within the corporate environment from which I mainly access my RDP Host via Guacamole. Not sure where the problem lies there as several components are involved ranging from Browser Isolation to Proxy with SSL interception etc. But all of this of course is of no concern to the Guacamole Team.

I’m using Guecamole for remote access RDP & SSL connection into my HomeLab and almost all is working just fine. The installation is using the official Docker images with Mariadb and is behing an nginx reverseproxy running in Docker as well. When I connect to a RDP host I get a working connection and almost all is fine just the keyboard is giving me problems. Both the connecting client and the RDP Host have the SwissGerman keyboard Layout. (https://en.wikipedia.org/wiki/QWERTZ#Swiss_(German,_French,_Italian,_Romansh),_Liechtenstein,_Luxembourg) When I started typing I noticed some reproducible problem using the special characters. If I start typing the keys from the top character row from left to right I should get: qwertzuiopü However I do get: qwertzuiopüüüüüüüüüüüüüüüüüü and I have to press any other key or backspace or so to stop the repeated üüüüü from coming. If I immediately try again to do the same I just get: qwertzuiop and the ü does not work After a minute or so of waiting I can type the ü again and get it to show up. But that trick works only once or twice then stops working completely and from there on I have to use copy paste to get these characters. What version of Guacamole are you using and what platform and browser is being used on the client side when you see this behavior? When this behavior occurs, is there anything unique about the keyboard in use? Or is the keyboard just a standard, hardware keyboard?
