Hi - I have an odd issue. My ELK stack is working perfectly fine, except for one index pattern that randomly stopped working shortly after upgrading to 6.6. I can hit http://elasticsearch:9200/flow-*/_search and get results and the indexes are responding individually as well.
Any idea what to try next? I have of course restarted the servers, reinstalled templates, and even blew away the data and had a new index start with no luck. All other indexes that do not match that pattern work and return fine...I am so confused.
Any help is appreciated.
