try connecting with port number. for ex, servername\instancename,portnumber
or
ip\instancename,portnumber(if its non cluster and have more than 1 sql instance)
or
ip,portnumber when server is cluster server and you have dedicated ip for your sql instance.
also,
ensure the default database configured for the account exists in database server.

Make sure the SQL Browser service is running at the time this error occures.

Please check whether there is a network breakage or packet loss to the Server machine where SQL is installed.
