Cannot create index using ElasticSearch.Net

Elastic Stack Elasticsearch

Hi!

I'm trying to create an index using ElasticSearch.Net but it does not work.
I have connection to Elastic since if the index exists I can send a query against it and get a result but when I try to create I get a ping error:

System.InvalidOperationException: CreateIndex in RotatingIndexClient received an 'invalid' response: Invalid NEST response built from a unsuccessful () low level call on PUT: /webtest12epi_2?timeout=1m

I have also used a WebClient and sent a request against http://sthlm-04:9200 and that also works just fine.

These are newly installed servers and we had to open the port 9200 to get it to work, could it be some firewall issue? We have older machines running the same code that can create index at sthlm-04.

Elastic is 8.2.2 and NEST and Elasticsearch.Net is 7.17.2

Thanks!
