TransportError(403, u'cluster_block_exception', u'blocked by: [FORBIDDEN/12/index read-only / allow delete (api)];')

Try GET yourindex/_settings, this will show yourindex settings. If read_only_allow_delete is true, then try:

PUT /<yourindex>/_settings{  "index.blocks.read_only_allow_delete": null}

I got my issue fixed.

plz refer to es config guide for more detail.

The curl command for this is

curl -X PUT "localhost:9200/twitter/_settings?pretty" -H 'Content-Type: application/json' -d '{  "index.blocks.read_only_allow_delete": null}'

elasticsearch elasticsearch-5

Last month I facing the same problem, you can try this code on your Kibana Dev Tools

curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'

I hope it helps

elasticsearch elasticsearch-5

I had faced the same issue when my disk space was full,

please see the steps that I did

1- Increase the disk space

2- Update the index read-only mode, see the following curl request

curl -XPUT -H "Content-Type: application/json" http://localhost:9200/_all/_settings -d '{"index.blocks.read_only_allow_delete": null}'
