OK. I have found out something:
The iframe is actually loaded like this:
iframe.set('src', (config.secure ? 'https' : 'http') + '://' +
config.frequency + '.' + config.server + '/?[{"cmd":"script","params":
{"domain":"' + document.domain + '","scripts":["' +
config.scripts.join('","') + '"]}}]');
If the config.frequency goes beyond my own maximum config.frequency,
the it is not loaded and that's what happened to me.
On my dev environment, I use a hosts file on Windows (instead of a DNS
service that will deal with the wild card *) and I only have a limited
number of entries.
Mystery solved.
Now I should not receive this error online as I have a DNS service
obviously.
Glad I understood this one.
