I had this issue with the rclone version from ubuntu

$ rclone --version
rclone v1.53.3-DEV
- os/arch: linux/amd64
- go version: go1.18.1

Updated to v1.62.2 through the script installation resolved the issue 👍.

I had similar/same issue using current Ubuntu distribution version:

rclone v1.53.3-DEV
- os/arch: linux/amd64
- go version: go1.18

on SSH access to local container using public key auth. Upgrading to latest executable from website fixed this for me.

rclone v1.59.2
- os/version: ubuntu 22.04 (64 bit)
- os/kernel: 5.15.0-48-generic (x86_64)
- os/type: linux
- os/arch: amd64
- go/version: go1.18.6
- go/linking: static
- go/tags: none

Thank you.
