I cannot add container because of error

Hello guys,
I wanted to run the netfoundry:ziti-tunnel container on my hapac2.
At first I pulled the .tar to my PC and put it in the external storage of my router.

After that I applied the configs as in the following tutorial:
https://support.netfoundry.io/hc/en-us/articles/4411874341389-Installing-Ziti-edge-tunnel-on-MikroTik-Router-Docker-

After this I wanted make the last step to add the container but I got errors as in the title:

I thougt that I maybe pulled the .tar with the wrong architecture (my router has arm) so I made another .tar-File with the following command:

docker pull netfoundry/ziti-tunnel:0.27.2 --platform linux/arm/v7

I added it into the Files again and I got the same error.
Does someone now what I am doing wrong?
I appreciate every help:)

The “lost+found” directory is where fsck puts damaged file fragments when it detects data corruption. Files placed there aren’t meant to be used as-is.

Container images being what they are, there’s zero reason to try recovering a damaged file. Just go download the immutable image again.

I tried but it did not work. I tried now to download the container over the remote image with this: “netfoundry/ziti-tunnel:0.27.2”.
I got a container but the status is on “error”. I tried it many times but it gave me always a container with status “error”. Looking at the os and arch its on linux/arm. So pulling the wrong image should not be the problem.

Edit: It was the wrong storage. After defining the root-dir the container got added with status “stopped”.
