Opensearch connection broken

[Techie4devops]

I couldn't able to connect bitbucket with OpenSearch. 

Please refer the below link where followed to configure.

https://confluence.atlassian.com/bitbucketserver/install-and-configure-a-remote-opensearch-server-1115664379.html#InstallandconfigurearemoteOpenSearchserver-connectStep4:ConnectOpenSearchtoBitbucket

Moreover, I running the stand alone OpenSearch container(opensearchproject/opensearch:2.0.1) on top of the ubuntu.

Below is relevant text from the atlassian-bitbucket.log file.

Necrobump, but in the event that someone else googles this as I did: OpenSearch 1.3 is the latest supported version at this time. OpenSearch 2.x is not expected to work (yet). Install OpenSearch 1.3 and try again.
