From: Brad Turnbough <bturnbo...@backlundinvestment.com> Sent: Tuesday, July 23, 2024 10:31 AM To: user@guacamole.apache.org Subject: Assistance in troubleshooting unsuccessful RDP Connection An RDP connection that was previously working is now no longer working. We have probably around 60 RDP connections configured and this is the only one not operating correctly. I have verified that I can indeed still RDP into the box using the windows native RDP client. What logs / debug flags / etc... need to be turned on and collected in order to provide meaningful information to troubleshoot and fix this issue? Thanks, Brad
