Hi Team,

We have two Petasan Clusters on two different Geo location. While adding the destination cluster at the source it says the connection test failed. But when the same Cluster node added and  acts as destination, it works.  Now i want this to be source Cluster and replicated data to different cluster.
 Meanwhile the log says Permission Denied

Make sure you read the replication guide in our docs.

check you can manually ssh from source replication node to destination cluster using remote ip, replication user name and key.

check you entered the key correctly in the ui. re-enter it do double check.

Hi Admin,
Thanks for the response.
I know this is a pretty straight forward process and have configured this and have performed many test cases between two clusters.
But in this case error still exists.
I tried the ssh which manually works using private key.
My networking part is also taken care, the vice versa works.
Can this happen if there is mismatch in the petasan Version. My source cluster version is 2.6 wich is lower compared to the destination  cluster which is 2.7.X

could this be causing the problem..?

i do not know, but it could be. i suggest you upgrade to 2.8X on both clusters and re-generate the replication key.
