Logstash on linux machine to read files from remote Windows folder

I have logstash installed on ubuntu machine and use file input to read log files.
I need read files from remote folder of Windows machine.

For more convenience I mounted
remote folder of Windows machine to my Ubuntu folder.
Now I can read mounted folder with any linux user.
Mounted folder has permissions 755.

But logstash "file input" doesn't see any files in this folder.
Currently I have simple logstash config.

input {
  file {
    path => ["/home/mount/test/*"]
    start_position => "beginning"
    sincedb_path => "/dev/null"
output {
  stdout {codec => "rubydebug"}

/home/mount/test - mount folder. I see here all files from Windows remote machine.
Could anyone help me with this problem?
How logstash on linux machine can read files from remote Windows folder?

I suggest setting log.level to trace and see what the filewatch module logs.

I put trace in log.level.
But I don't see any information about a problem.

If you successfully set log.level to trace you should be seeing voluminous messages like
