Getting the below error in Elastic 7.5.1 and readonly rest 1.19.0 version. I am using OSS Elastic and Open source read only rest verification.
SSL and Auth works fine but after enabling certificate verification for internode getting the error.The issue is my certificate has only hostname in it for port 9300. But with the error message it tries to look for ip or it looks for both hostname and ip and it is failing.
