Found the problem. My company has a palo alto networks application firewall. In reviewing logs between subnets that worked and subnets that didn't, the non-functioning subnets had a different application ruleset applied. Once the same ruleset was applied to those subnets, the connections resumed. One was based on web protocols, the other on system center configuration manager. While both were both port 8080 allowed, the non http traffic rule would immediately shut down traffic because it was not expecting the http protocol.
