Couchbase service stops automatically and the port 8081 is not working

I have installed Couchbase server and I was able to access the web console. Once I restarted my machine, I am not able to open the web console URL and when I tried netstat -a, I don’t see 8081 port. Also if I start couchbase service, it is getting stopped automatically. I could see the below error in Event viewer

“CouchbaseServer: Erlang machine stopped instantly (distribution name conflict?). The service is not restarted, ignoring OnFail option”

I am using Windows 10 and Couchbase version is 6.0.1.
