Server log might help in debugging. It would also help if you could add details about the configuration and what clients are being used.

Image

I have only a part of logs as the attached photo.
And about the client, I can’t describe details, it is SaaS(RPA)

400 typically means a bad request. You will have to get more information from the client.

If this is an ongoing issue you could use tcpdump or tcpflow to intercept the network traffic to determine what the client is sending.

Client is sending a request to recognize texts in images and return them. It is quite simple tasks, but just Ubuntu version returns periodically 400 while Windows passes all requests
