The last update I did was using this link:
http://teamcity.labkey.org/guestAuth/repository/download/LabkeyRelease153_Installers/.lastSuccessful/discvr/LabKey15.3-%7Bbuild.number%7D-discvr-bin.tar.gz

I'm not sure if I had this problem before this update as I didn't report this problem when I saw it the first time. I wanted to test a few things before.

All other updates and the original setup where from copies I picked on labkey.com
