Run time time out exception on couch base client

While updating the document we have been getting the time out exception.

couch base server version: 3.0.3 enterprise edition

couch base client - 2.1.2

Configuration:

connectTimeout: 10000
viewTimeout: 75000
queryTimeout: 75000

Env :

// Create couchbase cluster client
CouchbaseEnvironment couchEnv = DefaultCouchbaseEnvironment.builder()
.connectTimeout(configuration.getCouchbase().getConnectTimeout()) //10000ms = 10s, default is 5s
.viewTimeout(configuration.getCouchbase().getViewTimeout())
.queryTimeout(configuration.getCouchbase().getQueryTimeout())
.autoreleaseAfter(5000)
.build();

Code :
@Override
public UserDocument updateUserDocument(UserDocument userDocument)
throws Exception {
userDocument.setLastUpdatedTime(Calendar.getInstance().getTime());
JsonObject userDocObject = JsonObject.fromJson(gson
.toJson(userDocument));
JsonDocument userDocumentJson = JsonDocument.create(
String.valueOf(userDocument.getUserId()), userDocObject);
JsonDocument responseDoc = bucket.upsert(userDocumentJson);
// update device mappings in redis
if (userDocument.getUserDevices() != null
&& userDocument.getUserDevices().size() > 0) {
for (UserDevice userDevice : userDocument.getUserDevices())

{ redisClientService.putDeviceMappingInCache( userDevice.getDeviceId(), userDocument.getPartnerId(), userDocument); }

}
return gson.fromJson(responseDoc.content() != null ? responseDoc
.content().toString() : null, UserDocument.class);
}
