All of my build pipeline have stopped working in the last week without changes to the `config.yml`.  
This is the error message I am seeing for five out of seven of my pipelines.

```auto
#!/bin/bash -eo pipefail
yarn semantic-release

yarn run v1.3.2
$ semantic-release
[Semantic release]: Running semantic-release version 15.0.2
The authenticity of host 'github.com (192.30.253.112)' can't be established.

Are you sure you want to continue connecting (yes/no)? Too long with no output (exceeded 10m0s)
