On-Site Recovery

Gateway SSH Recovery

Restore remote SSH access to a 47Dynamics physical gateway appliance using a USB recovery assertion. No reboot required — the gateway stays online throughout the process.

Important Notes

The gateway must remain powered on and running during this process. Do not reboot.
The USB drive must be formatted as FAT32 or ext4. NTFS or exFAT will not work.
The file must be placed in the root directory of the USB and must be named exactly auto-import.assert.

Recovery File

auto-import.assert — Signed system-user assertion

auto-import.assert

This file is cryptographically signed by 47Dynamics. Do not modify, rename, or open it in a text editor!

Recovery Steps

Step 1

Download the Recovery File

Get the signed auto-import.assert file from the link below.

Click the download button below to get auto-import.assert
Save it to your computer — do not rename the file
The file must remain named exactly: auto-import.assert

Step 2

Copy to USB Drive

Transfer the file to a FAT32 or ext4 formatted USB stick.

Format a USB drive as FAT32 (Windows) or ext4 (Linux)
Copy auto-import.assert to the ROOT of the USB — not inside any folder
Safely eject the USB drive before removing it

Step 3

Insert into Gateway

Plug the USB into the running gateway appliance.

Locate any USB port on the 47Dynamics gateway device
Insert the USB drive while the gateway is RUNNING — do not reboot
Wait 30-60 seconds for snapd to detect and auto-import the assertion
You will hear/see no feedback — this is normal

Step 4

Verify SSH Access

Confirm you can now connect to the gateway remotely.

Remove the USB drive from the gateway
Notify your 47Dynamics administrator that the recovery is complete
They will verify SSH access using the new recovery key
If access still fails, re-insert the USB and wait another 60 seconds
