Who has a MegaLine provider (RK), how are things with the network?

Question

Computer networks

At first there was a problem with connecting to PuTTy via SSH. Fixed.
Now there is a problem with transferring files to FileZilla via SFTP. During the transfer, the connection cannot be established and the transfer is interrupted. Also, the agent cannot transfer the file to
me through mail.ru.
Among other things, the most popular VPN service sites do not open, as if they were specifically blocked.
ISP problem?
