I am in the process of consolidating some older daily indexes into monthly indexes, and this is working without issue for indexes that are less than 100MB in size.
However, now that I am working on rolling up larger indexes (approx. 800MB -1GB), I received the 504 timeout error. I increased the timeout to Elasticsearch from 60000 to 120000 and am now receiving this 'Failed to connect' error.
I am not aware of any proxies that may be in place.
Any pointers as to why I am seeing this error returned when reindexing the larger indexes?
The more details the better. It sounds like Kibana is losing connectivity with Elasticsearch (at least temporarily). I could be wrong, though. I've seen that happen in other edge cases.
