RSS Feed stopped working after server change

I had a blog that stopped working on a server where I couldnt get access to my database, which meant that I had to build a whole new blog from scratch on another server, and then point the old domain to that server.

Ever since I made this change, my RSS-feed isn’t working properly. I used feedburner to have a feed displaying the latest posts from my blog on another website. I have tried to get a new feed going, but when i type my domain in, the feed still displays the posts from the old blog instead of the new one for some reason.

I made the change over two weeks ago, so all the DNS settings should have been updated a long time ago. When I type the domain (https://www.trendybingoblogg.com) in to my browser, I come to the new blog, with the new posts. Any ideas of why this is happening?
