ACME DNS Plugin - list empty

[Sysxpp]

Hello!
I'm trying to add a CloudFlare plugin, but the list with plugins (DNA API) is completely empty, when I click on combobox arrow nothing happens, no list.
Any thoughts why this is happening and how to fix it are greatly appreciated!
Thank you!

Well, it turns out that after updating everything, it works as intended.
