Server machine: alliancechemical.com

Getting this error message when trying to run composer install Task in Trellis. Deleting my composer.lock file then trying to manually run composer install --verbose on client gives the following error ouput:

[Composer\Downloader\TransportException]
  curl error 35 while downloading https://{mydomain}/satispress/packages.json: error:14094458:SSL routines:
  ssl3_read_bytes:tlsv1 unrecognized name

Client's composer.json has this satispress repo set up:

 "repositories": {
        "satispress": {
            "type": "composer",
            "url": "https://alliancechemical.com/satispress/"
        }

Credentials are in a auth.json file

{
    "http-basic": {
        "alliancechemical.com": {
            "username": "{API_KEY}",
            "password": "satispress"
        }
    }
}

Not sure what's wrong here both client and server are provisioned with Trellis
