Sentinel Error

Hi, I have got my masternodes running , wallet sync etc but when I run the sentinel test  I get 19 passes and 1 fail which is test_monoecid

I have check the sentinel Github readme and run the debug and get the following

root@scw-6cb7c0:~/sentinel# SENTINEL_DEBUG=1 ./venv/bin/python bin/sentinel.py
2017-12-30 10:04:46 [info]: SCHEMA_VERSION (code) = [20170111-1]
2017-12-30 10:04:46 [info]: DB_SCHEMA_VERSION = [20170111-1]
-342: non-JSON HTTP response with '401 Unauthorized' from server
Cannot connect to monoecid. Please ensure monoecid is running and the JSONRPC port is open to Sentinel.

Monoecid is running and I can get status from
monoeci-cli getinfo
monoeci-cli mnsync status

Thanks
