Can't open multiple connections

Hello Tristis,

Thank you for contacting us on that matter!

Could you please provide us with the data source you are currently using?

If it is not too much trouble, could you please create a portable installation of RDM and verify whether this issue persists?

To do so, follow these steps:

1. Close RDM.
2. Access the link below:
Previous version - RDM - Devolutions
3. Find and download the portable version you want as a binary file.
4. Create a new folder on your Desktop.
5. Extract the .zip file contents into the folder created in step 4.
6. Once extracted, go to this folder and run remotedesktopmanager.exe.
7. Connect to your data source.
8. Replicate the issue.

This test helps us determine whether your local RDM installation is causing the issue.

Please note that if you are using an Advanced Data Source, it is recommended to skip step #7 and instead use the default data source created by the portable RDM installation.

Best regards,

Alexis

Hi Tristis,

Thanks for the quick reply.

Could you please provide us with the data source you are currently using?

Could you also share screenshots of the properties of the SSH sessions you are trying to run simultaneously?

Thanks for your cooperation.

Best regards,

Alexis

• nope.
• all custom fields:

yes, problem happens because of post-login commands. If clear tab, this hosts will open above the limit.

Hi Tristis,

I was able to reproduce the behavior you described.

I found a workaround to open SSH with post-login commands: just start an SSH session without the post-login commands, close it, and then open the one with the commands. It will open.

Meanwhile, I will inform our developers to fix this in the next version.

Thanks for bringing this to our attention.

Best regards,

Alexis
