Rclone Failed to rc: connection failed: Post "": EOF

What is the problem you are having with rclone?

while copying files from AWS to GCS, I get this EOF error. Running in GKE cluster.

Run the command 'rclone version' and share the full output of the command.


Which cloud storage system are you using? (eg Google Drive)


The command you were trying to run (eg rclone copy /tmp remote:tmp)

// running as a rclone webserver on a GKE cluster as kubernetes deployment:

I'm running the rclone as webserver on a GKE cluster and running a cronjob within the same cluster, to copy data from a AWS S3 bucket to GCS bucket, getting this EOF error. Sometimes it working and sometimes I get this error. There are lots of files that gets checked and then copies only the new files.

The rc command is timing out by the look of it.

You can increase --timeout, but a better approach is to start an async job

i will try, thank you ncw.
