Description of the problem including expected versus actual behavior:

Steps to reproduce:

1. I was previously using NEST/Elasticsearch.NET 7.13.1 to connect Elasticsearch 7.10 in .netcore3.1, and it`s work properly.
2. After upgrading .netcore3.1 to .net7, with the same NEST/Elasticsearch.NET and Elasticsearch, it`s work properly in my local VisualStudio（IIS Express），but it reports "The client noticed that the server is not a supported distribution of Elasticsearch" when deployed in Centos7.9.
3. I have tried to using NEST/Elasticsearch.NET 7.15、7.16、7.9、7.11、7.12...... but the result was still like 2
4. When i using NEST/Elasticsearch.NET 7.17.5, it reports "The client noticed that the server is not a supported distribution of Elasticsearch" both in my local VisualStudio（IIS Express） and Centos7.9
