Hi, I deployed a elasticsearch on Azure using [Elasticsearch (Self-Managed)](https://azuremarketplace.microsoft.com/en-in/marketplace/apps/elastic.elasticsearch?tab=Overview) I am using [NEST](https://www.nuget.org/packages/NEST) nuget package to communicate to elasticsearch api in a .net application. This my application works fine with elastic search hosted on aws. In case of Azure deployment I am getting below exception from elastic search when trying to refresh index. The nuget package is creating below request `response = await client.Indices.RefreshAsync(indexName).ConfigureAwait(false);` The above call creates below request. I captured it using WireShark ```auto POST /azureelasticindex_uact7de0dd994d174895bbdd8cff0a3a0123/_refresh HTTP/1.1 Accept: application/json Content-Type: application/json User-Agent: elasticsearch-net/7.4.1 (Microsoft Windows 10.0.19043; .NET Framework 4.8.4341.0; Nest) Authorization: Basic ******** Host: lb- ***********.cloudapp.azure.com:9200 Content-Length: 2 {} ``` In response of above request I am getting ```auto HTTP/1.1 400 Bad Request content-type: application/json; charset=UTF-8 content-length: 357 {"error":{"root_cause":[{"type":"illegal_argument_exception","reason":"request [POST /myindexname/_refresh] does not support having a body"}],"type":"illegal_argument_exception","reason":"request [POST /myindexname/_refresh] does not support having a body"},"status":400} ``` also if create same request using kibana-console I am getting same error on Azure but on AWS everything works fine **Azure** ![image](https://us1.discourse-cdn.com/elastic/original/3X/c/6/c644e389988f5f77cb76973a3375021ff10028e9.png) **AWS** ![image](https://us1.discourse-cdn.com/elastic/original/3X/1/a/1a481231d92858df5f890e2dee04f2d94568805c.png) What is the problem here? ---

Welcome! In the screenshot you shared for Azure, you are calling `GET` instead of `POST`. Is that expected? ---

Thanks for pointing out for wrong capture. By mistake I clipped wrong image and put in the post. I have corrected the image. ---

I suspect that there's a proxy or something like that in the middle? It looks weird indeed. ---

What is the output of ``` GET / ``` On both clusters? ---

I would also guess that a proxy along the way may be removing this empty content. I noticed from the output that you are using NEST 7.4.1. The latest versions no longer send empty objects in the request body. The clients are backwards compatible with the previous 7.x versions of Elasticsearch, so I'd recommend updating to 7.13.2 which should resolve the issue here. ---

hi, thanks for you replies. The issue was version of elastic search. On AWS installed version is 7.9.1. In this version \_refresh api supports body. On Azure I installed 7.11.1 and in this version body in \_refresh api is not supported. To use 7.11.1, nuget packages must be updated. Latest nuget package is not sending empty body in \_refresh api. Currently to work with our code I installed elasticsearch 7.9.3. and this version also supports body in \_refresh api. Thanks again for your support. ---
