Reporting Services running locally but not on the network

We had a Active Directory fail. We have since fix this but reporting services url doesn't work across our the new work. 

If i browser on the local PC http://127.0.0.1:8081/ReportServer/Pages/ reporting services work fine. 

If try an accessing reporting services from another PC using the server name or IP i can't get to work.

http://serverdata02:8081/ReportServer/Pages/ or http://192.168.1.192:8081/ReportServer/Pages/
