Just upgraded to 2023.2.14.0 64-bit and Open with a Template is no longer working. Have several embedded putty ssh hosts and the templates are just an alternate login method using embedded telnet but $HOST$ is not populating from any host entry that is trying to be opened with a template. Have tried several different settings changes and refreshes but continue to get an error stating "The host is required". Have 4 of these templates that worked without issue on previous versions of RDM.

Seems like there is same problem passing variable to external application just posted in Winscp Template not working in 2023.2.14.0 64 bit windows 10 (devolutions.net)
It seems a similar problem we have spotted just yesterday (same RDM version of the original poster), in that we created a sub-connection of s a Web site to access the underlying appliance but via SSH. Even tho' on the Web site's entry dashboard the value for the Host is clearly and correctly computed (from the site's URL), in the sub-connection inheriting the host or even using $PARENT_HOST$ lends to the same error message reported.
Hello,
Thank you for contacting us on that matter.
I'm sorry to hear that you're experiencing issues with Variables. I will open a case for the engineering department regarding this issue to get it resolved as soon as possible.
In the meantime, could you provide the application logs? This will help us identify the root cause of the problem and find a solution.
Also, I suggest trying a portable version of RDM version 2023.2.9.0. To do so, please follow the steps below:
1. Close RDM.
2. Download the .zip file from the following URL: https://cdn.devolutions.net/download/Devolutions.RemoteDesktopManager.Bin.2023.2.9.0.zip
3. Create a new folder on your Desktop.
4. Extract the content of the .zip file into the folder you just created.
5. Go to the folder where you extracted the files and run remotedesktopmanager.exe.
6. Connect to your data source.
I hope this helps and please let me know if you have any further questions or concerns.
Best regards,
Patrick Ouimet
