VPN Hydra + browser = some sites almost inaccessible

Am I the only one having problems with new version of F-Secure VPN, with Hydra option, and browsers having difficulties to open up some pages?
On some sites, for example finnish national broadcasting company yle.fi is unreachable unless I type in the https-part as well (https://yle.fi) to the address. And to make matters worse, the page takes sometimes forever to load, if it even loads at all. Sometime when I keep hitting refresh, the site eventually loads, sometimes that doesn't work either. If I disable the VPN, the site opens up without any problems.
I've seen the same effect on Firefox and Edge. I'm using Windows 10 and F-Secure Total.
If the site opens, it seems to work almost normally, there are sometimes additional delays with loading images, videos etc..
