Unfortunately no I cant access,
I noticed that this situation occurs if i deleted some docs from the couchbase server node,
does it affect the credentials?
In general, you shouldn’t directly delete any documents in the bucket used by Sync Gateway - any deletes should be done through the Sync Gateway REST API.
Sync Gateway also stores all of its non-application data (users, roles, sessions, replication checkpoints, and more) in the bucket.
While developing, if you want to clear everything out and start fresh, you can flush the bucket, but you’ll need to restart Sync Gateway.
Some more detail: The users section of the config file is only used when SG launches, to create the initial user account(s). Incoming requests are never authenticated against what’s in the config file, only against the live user account data stored in the bucket.
And let me repeat the important safety tip: never modify Sync Gateway’s bucket yourself, except for flushing it completely after stopping SG.
