If you’re using Ansible Tower on Red Hat 7 or CentOS 7 you might see the yellow-mark on the top right page saying: “Live events: error connecting to the Tower server” or get errors when using the API (And the web-interface is one big graphical API) when adding groups, giving a ‘500’ error. This is a known issue, and you can do the following to step back python’s ssl handling package:

rpm -Uvh --oldpackage http://bo.mirror.garr.it/1/slc/centos/7.1.1503/updates/x86_64/Packages/python-2.7.5-18.el7_1.1.x86_64.rpm \
http://bo.mirror.garr.it/1/slc/centos/7.1.1503/updates/x86_64/Packages/python-devel-2.7.5-18.el7_1.1.x86_64.rpm \

# Once you do that, restart the tower services:

ansible-tower-service restart
