Wrong RSS link

Hello all.

I have my blog at https://fractura.net .
As RSS you will find a link at the top of the page: https://fractura.net/feed .
This RSS feed is not recognized by Feedburner (https://feed2.feedburner.com/fracturafeed), which maintains the old one as the original, from https://blog.fractura.net/feed .
If I try to change the original feed, it appears a 404 error.
Also, if I try to auto detect it, it will give me the old feed.
I tried already with RSS2 URL, but it doesn’t let me change it.
Please notice that blog.fractura.net, doesn’t exists anymore.
So, by now, I’m posting without any feeds, because I can’t find a valid one for the present URL…
Help, anyone?…

Thanx!
