Nothing worked ☹ Neither TLS nor NLA The ignore_cert=true is set on the connection
Now not even provide errors on daemon.log… The strange is that my version 0.8 works like a charm… Why not the 1.5.5? Are there any log files that I could send you?

Please verify that this is actually set for the connection that you're attempting to open. Also, the actual connection parameter within Guacamole Client should be "ignore-cert" (- vs. _).

We decided to deploy our environment on last version 1.5.5 ad move into it, since upgrade from 0.8 on a centos 7 to 1.5.5 it seemed crasy. Wow, that's quite a leap :-). We deployed a guacamole 1.5.5 on Debian 12 with Database mariadb and active directory integration, using tomcat apache 9. When I am testing the recreated RDP connections I get the following on daemon.log (this connection is against an old windows 2008 R2 Terminal server that I can access pretty fine from guacamole 0.8): Jul 19 10:56:44 srvv2shqpgua02 guacd[2417]: Security mode: Negotiate (ANY) Jul 19 10:56:44 srvv2shqpgua02 guacd[2417]: Resize method: none Jul 19 10:56:44 srvv2shqpgua02 guacd[2417]: No clipboard line-ending normalization specified.
