Is there any way I can retrieve my old server?

I created my server in August last year, I didn't use it for about 5 months or so and when I went back to the Aternos site it was gone.

Is there anyway I can retrieve the old files or something?

Data retention of server data

If you don't have a backup, no.

There is no way I can retrieve the old world files even from my minecraft folders?
