We have recently migrated our couchbase from 6.5.1 to 7.0.0. Now we are trying to migrate to 7.0.1. The upgrade process says it was successful. But when we try to access the UI ( IP:8091 ), it is not showing up. Would you please let me know how to troubleshoot and see what’s happening?. The couchbase is running on an AWS EC2 ubuntu 18.04 machine.
