hi @wanda_a, when you say you used more than one data node and based on the link you provide, I assume that you are using 3 couchbase server nodes in the cluster. Could you let me know how many sync gateways you are using?
Btw, were you able to add all 3 couchbase server nodes in sync gateway config file which you referenced the link
in your sync gateway config file, add all 3 server ips of sserver cluster
“server”:“http://11.111.11.111,22.222.22.222,33.333.33.333:8091”,
