Can't download WU

It's another day I can't download a WU. The log says:

====================
What can be the reason?
Is there any way to fix this?

The solution was to set up a VPN to connect to 144.121.86.56. Obviously, F@H servers reject attempts to connect to them from Russia.

Or the institutional firewall at the research institute where the F@h server is located is blocking a range of IPs that corresponds to your ISP.
