Oh! I missed this! Thank you!
Now slave reached consistent state some time after start, but still
no connection to master server and still restoring wal-files.

Not quite sure what you are getting at.

You are not seeing the streaming connection happening?

Yes, no streaming connection.

If a connection is not being made:

1) Dose user replication have REPLICATION rights?
2) Is the pg_hba.conf on the master set up to allow a connection from
the standby for user replication and database replication?

I commented 'restore_command' in recovery.conf and after start slave
connected to master.
Then I uncomment it back. Is it possible to have a both, streaming
connection and restoring from wal files from NFS share?

Yes:

I wonder if your master is recycling WALs fast enough that the streaming can't find them and the standby has to go to the archive instead.

What is your wal_keep_segments on the master set to?:

Where are the WAL files coming from?

NFS share on master.
