FetchSFTP cant retrieve files correctly: java.io.IOException: error; routing to comms.failure

[#1]

I'm trying to get a set of file .csv from a directory in a server sftp. My nifi is deployed in a cluster with only one node for nifi. If I try to download a file .csv through sftp> from the same node on which nify is deployed, I can get it without problem. However the processor SFTP in nifi is not able to do it, but I continuosly get the following stacktrace

ERROR org.apache.nifi.processors.standard.FetchSFTP: FetchSFTP[id=1f5b3ddd-2d4c-1889-ffff-ffffa3d58254] Failed to fetch content for StandardFlowFileRecord[uuid=ccf2a3ae-51cc-470c-80e0-6477b045a536,claim=,offset=0,name=file.csv,size=0] from filename /test/nifi on remote host 10.100.201.248:22 due to org.apache.nifi.processor.exception.ProcessException: IOException thrown from FetchSFTP[id=1f5b3ddd-2d4c-1889-ffff-ffffa3d58254]: java.io.IOException: error; routing to comms.failure: org.apache.nifi.processor.exception.ProcessException: IOException thrown from FetchSFTP[id=1f5b3ddd-2d4c-1889-ffff-ffffa3d58254]: java.io.IOException: error

Can someone helps me? in the FetchSFTP I put the same configuration used to get the file using sftp> thus those are correct. Could it be due to misconfigurations of nifi in the cluster? im using Cloudera
