Could not fetch config from bucket

I see in my log this exception:
2017-01-05 16:42:13 DEBUG CarrierRefresher:111 - Could not fetch config from bucket “service” against “couchbase01-xxx/”.
com.couchbase.client.core.RequestCancelledException: Could not dispatch request, cancelling instead of retrying.

Why ?

@Alessandro.79 this exception is just the effect of a different cause. What is happening in your system, in which stage are you? (bootstrap,…) can you share more logs that give us more infos?

@Alessandro.79: Did you work this out? Any more context so we can help?

We met this same error. Finally, we replaced the java client SDK with a newer version(2.5.2), and it’s fixed! I think it may hit some bugs of SDK 1.x.
