Description

I have an on premise Guacamole Server which was running version 1.2.0 in Debian 10 buster without any issue. However, after upgrading to version 1.3.0, using guacamole-server source code and guacamole-1.3.0.war downloaded from official website, I cannot connect to any of my servers using RDP. 

Looking at /var/log/syslog, I get the following:

Looking at /var/lib/tomcat9/logs/catalina.out, I get this:

No exceptions nor errors. This is what I get in my screen:

FreeRDP version is the following: freerdp2-dev is already the newest version (2.0.0~git20190204.1.2693389a+dfsg1-1+deb10u2).
