Stuck on Syncing parcel repositories

[#1]

i click "Check for New Parcels" or use swagger api "refreshParcelRepos", clourdera manager can not check out  new parcels in my local repository. But it can check out new parcels when i reboot clourdera manager server. how can i figure out why it is stucked on "Syncing parcel repositories" or how can i get some useful error log info.
