Authentication problem with CouchbaseNetClien >= 2.7.8

Hello,

We’ve faced problem with authentication after update CouchabseNetClient to 2.7.8 (also we’ve tried 2.7.11).
Exception message is “Authentication failed for bucket ‘bucket-name’”.
We use Couchbase Server 5.1.0 build 5552
With CouchabseNetClient 2.7.7 works as expected.

Is it bug or not?
Thanks.

I found the problem, there was mistake in creds.
