Unable to Upload File

I run kibana 7.10.1 on windows and have ES 7.10.1 on my linux machine , I configured ES IP on kibana.yml to connect and when i run the kibana there are some errors but I can open kibana on my browser and see sample data that i added a week ago into my kibana .
errors:

[18:00:05.436] [error][data][elasticsearch] [version_conflict_engine_exception]: [task:Lens-lens_telemetry]: version conflict, document already exists (current version [19])
  log   [18:00:05.447] [error][data][elasticsearch] [version_conflict_engine_exception]: [task:Alerting-alerting_telemetry]: version conflict, document already exists (current version [19])

and when i want to upload a csv file (size : 200 KB) in the kibana terminal it raises some timeout error :

[17:54:47.750] [error][data][elasticsearch] [TimeoutError]: Request timed out
  log   [17:56:47.753] [error][data][elasticsearch] [TimeoutError]: Request timed out
  log   [17:57:01.592] [error][data][elasticsearch] [TimeoutError]: Request timed out

  log   [17:59:01.593] [error][data][elasticsearch] [TimeoutError]: Request timed out

and my connection with ES on port 9200 is OK too and i can see http://myES:9200/ too

some errors again when i upload file :

[18:27:30.855] [error][data][elasticsearch] [timeout_exception]: Aborting structure analysis during [multi-line message determination] as it has taken longer than the timeout of [25s]

Can you elaborate a little more on what file you are trying to upload?

A csv file

And where are you trying to upload to exactly?
How big is the file?

If you can provide a bit more context it'll help us to help you :slight_smile:

The file size is 200 KB and it is csv
And i try to upload it in kibana main window
Where there are add data and after that it is upload file
