Hello, with the new 5.4 i wanted to try ML which led me to update some field types thus i am re indexing, while doing noticed some stuff wanted to ask if you guys had any ideas, using the basic code at kibana dev tools: POST \_reindex { "source": { "index": "twitter"}, "dest": {"index": "new\_twitter" } } 1 issue is if i use kibana over nginx, it times out 2 no errors but the number of docs is different ![](https://us1.discourse-cdn.com/elastic/original/3X/0/d/0dda2e87862dbf3cefaaff9617805cee989259eb.png) 3 Another reindexing - the doccument counts match but its deleting something no idea what 😕 ![](https://us1.discourse-cdn.com/elastic/original/3X/3/4/34bc7e8bb317fd6e1c361ab05bd426bf102acbab.png) ps this one also gave en error on kibana 😕 "back end cant be reached" any ideas info would be much appreciated everything is 5.4 on cent OS 7 ---
