Addendum:
1) How long does it take for an entry to appear on the map? I manually
entered the following URL into a browser (three times) but I don't see it on the map (CA, USA). http://44.182.21.1:59001/generic?id=n6mef@cm97aj
For entries to be accepted, the sender needs to be in the 44net address space. Otherwise http notifications will be ignored. This could be a possible cause.
