Kibana Table visualisation search error

please help me with this error of the table visualisation

the table was working for a long period of time an then it started showing an error message of type 'search error'

There must be something in the logs when this error occurs, can you please share more details - logs, steps , size of ur instance etc.

have you verified that Kibana is up and running? what is the output of curl -XGET localhost:9200/_cluster/allocation/explain?pretty

Thanks
