feed problems?

Some feed websites (like feedly) can find my blog, and shows updated posts. Others like Bloglovin doesnt work AT ALL. it says I have no posts at all. Bloglovin told me that the feed is “too slow”and I should “burn a new feed at feedburner” and send it to them, but if I go to feedburner and try that, it says “we could not find a valid feed at that address”. I can then confirm its validity and that is fine. But feedburner and bloglovin’ dont find my feed/posts at all.

the website is https://sovanisa.com

help!?! any ideas?!?! I really dont understand this at all…
