strange registering behaviour on osmo-bsc

Dear list, I test again with new build for osmo-bsc osmo-msc-osmo-hlr I dont know if the osmo-hlr and osmo-bsc has been fixing or I have mistake for configuration which I did not change from the success I test before, but now I cannot register my phone and even make the network error and keep on emergency only when registering on the phone. at osmo-hlr I got this : 20180201190135844 DAUC <0003> hlr.c:79 510106127044410: IMSI known, but has no auth data; Returning slightly inaccurate cause 'IMSI Unknown' via GSUP Does the new osmo-bsc on master cannot use? or maybe I need to investigate more? Thanks for any feedback! -- Best Regards, DUO
