Dear Sir/Madam, We’ve been using ATC 1.7 on CentOS 6.5 and now we are trying to use 2.0 on CentOS 7. Unfortunately, during the installation of traffic_ops it always says cannot connect and the status code of 500 is shown. `service traffic_ops status` always is showing being offline whilst the service is started! With the version 1.7 on CentOS 6.5 we have no problem, but this problem occurs on CentOS 7 with the versions of 1.8 and 2.0 . Please let us know what the reason is and how we can fix it.
Yours Sincerely, Vahedi
