I am using the master branch, but I cannot SSH because of an error.

Please provide the following information.

1. Your hosting provider information, such as DigitalOcean, Linode, AWS, or GCP.
2. The version information of your host's SSH service.
3. The information from your host's SSH configuration file.

1, https://www.shin-server.jp/
2, OpenSSH_8.0p1, OpenSSL 1.1.1k FIPS 25 Mar 2021
3, I cannot access the SSH configuration file because I do not have root privileges on the server.

Instead, I can give you the SSH connection password.

Similar problems encountered. In my case, it was due to the SSH settings on the rental server. Due to security enhancements on the rental server side, SSH had been changed to ‘only allow access from within the country’, so I changed it back to ‘allow access from outside the country’ and solved the problem.

A bit of context, I am using ed25519 generated on my local machine and I added the public key to the Digitalocean ubuntu serve ~/.ssh/authorized_keys. I also added the private key to github secrets and below is my workflow

run-name: Code deployment to staging by ${{ github.actor }}

on:
  push:
    branches:
      - staging

jobs:

I'm having the same issue as @menadio, also on a DigitalOcean VM.
Scratch that, I had the username set incorrectly, appears to be working now.
