Domain not available to register SSL certificate after app is created

[adriantoll]

When using a Bash script to create an app, promote the main domain to primary, and register an SSL certificate for that domain, the certificate registration doesn't work. (See issue #38 for the reason behind the command under "Remove invalid line at end of variable"). This is the script:

# Create the app
app_json_object_raw=$( atomic apps:create "$account_id" "$site_url" "$site_url" )

# Remove invalid line at end of variable
app_json_object=$( sed '/^\[/d' <<< "$app_json_object_raw" )

# Get app id from json object
app_id=$( jq '.[ "id" ]' <<< "$app_json_object" )

# Get domain id from json object
domain_id=$( jq '.[ "aliases" ][ 1 ][ "id" ]' <<< "$app_json_object" )

# Set primary domain
atomic apps:domain:make-primary "$app_id" "$domain_id"

# Register SSL certificate
atomic ssl:le:register "$account_id" "$site_url"

When trying to register the certificate I get this error:

In RequestException.php line 113:

I also get an error when trying to register the certificate for the domain through the Atomic control panel after that command is run. I presume this is something to do with timing, as if I wait a few minutes then I can issue the certificate through the control panel.

Further to this, I just ran that script without the SSL cerficate command, went to register the SSL certificate in the Atomic control panel, and I can't even pick it from the list of available domains despite it being registered with the app. So it looks like it takes quite a while (in relative terms) for the domain to be available to other services.
