Vivaldi Mac and HTTPS
A while back, I tried setting up my personal website with Let's Encrypt. I wasn't able to get it working, and removed the encryption from my website, so now when I enter the url, it should automatically redirect to an http:// site instead of https://. This happens in every other browser - except Vivaldi. Even when I delete cookies/history, and try to force refresh the page, Vivaldi still tries to retrieve a secure version of my site which doesn't exist. Is there some way to force Vivaldi to serve the non-secure version? Thanks in advance.
You used HSTS and SSL? So the browser caches the SSL certificate.
In section Delete domain search for the domain you want to get rid off
That should work.
