Please, do tell me if it does not resolve your issue.

Best regards,

Problem is still here.

Ah! Of course, there appears to be a bug on our side. I'm opening a ticket.

We'll post back when a version is available with the fix.

Hi ratko,

As of today, RDM 2022.1.3.0 is available and "Skip environment variable setup" should work properly now.

Please, do tell us if it's not the case, or for any other issues.

Best regards,

Hi Xavier.
Now my SSH connection Cisco IOS-XR works perfectly. Thanks!

Ratko

Glad to hear it!

Do not hesitate if you have any issue/questions.

Best regards,
