Patreon login on wordpress site

Hi everyone, I am using wordpress on my website where I also have a webshop with woocommerce. I’m using the patreon plugin to have my patreons get discounts in my webshop.
The webshop is about to be moved from shop.haillogknall.no to haillogknall.no/butikk. Its on the new url where I am experiencing login troubles. My patreons are sent in a loop between the /patreon-authorization/ and the redirect-service (url: https://haillogknall.no/patreon-flow/?patreon-login=yes&patreon-final-redirect=https://haillogknall.no/butikk/)
This is pretty annoying and I cant get my head around whats wrong. I’m not a developer but have to sort this out myself.
Would really appreciate any help on this issue.
