Hey, @NSTR 
I hope you fond a way to get this resolved. I’ll leave a few notes here as well.
From your screenshots, it looks like you’re using a non-HubSpot from and the non-HubSpot Forms tool. The no cookie error is telling us something on your page is blocking the HubSpot Tracking code from setting the cookie properly. But you’ll need a dev or dev resources to look at your page and see if you can spot the issue. This part of the knowledge base covers some common reasons your form submission may not work. The limitation is that with external pages and forms, there are too many variables out of HubSpot’s control to list all the potential causes.
Best,
Jaycee
