elasticsearchmagento2magento2.1.6save
Every time I save a new product I get that error
"No alive nodes found in your cluster"
My version of magento is 2.1.6 and the problem appeared after installing the elasticsearch module
What could be a solution to this problem? this also does not let me delete products or change their data
The problem was that some hidden fields, that are part of the product form, were not opened. There is an "Advanced price" section under the price input field, in which there are additional input fields present. One of them was mandatory. Unfortunately, Magento says nothing about why the click on the "Save" button has been discarded.
If you are using Magento and getting 'No alive nodes found in your cluster' error while reindexing.
Make sure you have updated following :
'[host]:[port]'. Eg: 'es-node1.fqdn:9200, es-node2.fqdn:9200' or 'localhost:9200' in System -> Configuration -> Elastic Configuration.Try this, and clear cache and reindex. It will solve your issue.

There are two things you should check.
Check the elastic search hostname and the port are correct and accessible.
telnet elastic-search-host port
Run full reindex, which will create elastic search nodes during indexing.
