Getting No response from server on Read file from SFTP - second call

What are you trying to achieve?

HI,
I’m reading files from SFTP. I read one file, process it, and then read the next. Sometimes the second Read File module fails with “no response from server”. The file exists and the server is available. I added a delay for 20 seconds but still getting the error.
Thanks.

Steps taken so far

Added a 20 sec delay between each read
