I would be rather surprised, or indeed horrified, if it continued the download after a cert check failure.
In case you are not aware, if the download does not occur logstash will stop doing geoip lookups after 30 days, you will have to switch to a manual download. After 25 days I believe it starts warning that this deadline is upcoming.
Yea, I read where it will fail, but there is little info on debugging why it fails. I've turned up logging to "trace" for the next day's errors. BUT, other parts of ELK have options to skip cert verification, can't find any options or defaults for this plugin however.
