Okay, I figured this out, and the cause is completely unrelated to RDM. :)

The issue was the PPK files. When I said my new instances stopped working, the problem was not that I updated RDM or changed my EC2 images, but that I updated PuTTY. As of version 0.75, it uses a new key format (v3) which appears to be unsupported in the version of RDM I am using. So any keys I generated using puttygen since the update don't work.

I have converted my new keys to the v2 format, and RDM is now working fine. Perhaps in the future you might consider supporting v3 PPK keys, but for now, everything works.

Thanks for all your help!

Please see here. Alignment might be a bit off near the end as I had to stitch two screenshots together (wouldn't fit entirely on my screen).

Thanks!

Hi James,

Thanks for the tips. I tried this and unfortunately the result was the same.

Hello,

Thanks for your quick response.

I tried the above script, and the result is the same. :(

I'm using the free edition.

Hello,

First of all, thanks for this excellent product. As an admin with both Windows and Linux VMs I use it a lot.

I had an old version (2019 or so) on my old laptop, and all my SSH connections worked great. I got a new computer recently and installed 2021.6.10.1, and now I cannot connect to any of my recently-created AWS instances.

The following appears in the log:

[2021-07-16 12:43:48 PM] Devolutions Protocols version: 2021.6.10.1 Windows
[2021-07-16 12:43:48 PM] Starting SSH, verbose level: 2

[2021-07-16 12:44:09 PM] SSH Error sending raw output
[(10057L) A request to send or receive data was disallowed because the socket is not connected and (when sending on a datagram socket using a sendto call) no address was supplied.]
[2021-07-16 12:44:09 PM] Disconnection in progress
[2021-07-16 12:44:09 PM] Disconnecting

The machines are all running CentOS 7.5 and I am able to connect to all of them with PuTTY. I'd love to be able to get these working in RDM. I've tried enabling all algorithms and disabling the "skip environment variable setup" option which seemed to work for others, but it didn't work for me.

Thanks in advance for your help.
