Dear All,

currently I have 2 clusters, I want to move data from cluster A to cluster B using the "reindex remote cluster" method. but it happens when running.

 ![devtools](https://us1.discourse-cdn.com/elastic/original/3X/b/e/be133133940f170fe8fdaa40879a3dbc30947d8d.png)

and when running curl on the local server and trying to access the remote cluster the results are as below.

```auto
[root@loc-master1 ca]# curl --cacert /etc/elasticsearch/certs/ca.crt -u elastic 'https://192.168.12.156:9200/_cat/nodes?v'
Enter host password for user 'elastic':
curl: (51) Unable to communicate securely with peer: requested domain name does not match the server's certificate.

```

can someone help me solve this problem? I am very confused.

Best Regards,  
Septia

Hi @Septianingrum.17

Run that command again with `-v` and share the output. Pretty sure you have a missmatch in the certs SANs / IPs.

Please show the command in the full output
