Installing and updating the FAQ

I'm trying to download Octo Browser from the site, but unfortunately nothing happens after the click or the site is unavailable and does not open

  • Check if your antivirus is blocking access to the site (Avast / McAfee have been seen in absurd actions). Check if you have the latest antivirus updates (application / database).
  • Turn VPN on or off. Perhaps the ip address of the server is in the ban of your provider. The site uses CDN CloudFlare (often RKN contributes entire subnets of CloudFlare ip addresses). We recommend choosing VPN server locations in Europe (DE, AT, NL, PL, CZ), while taking into account and checking the VPN speed, if it suddenly seemed to you that something was running slowly (perhaps the issue is precisely the load of the selected VPN server)
