When encountering the HTTP Error 503 Service Unavailable in SSRS Reporting Services, it is crucial to identify the root causes to effectively fix the issue. One common cause of this error is the application pool being stopped or disabled. To address this, you can go to the Internet Information Services (IIS) Manager, select the application pool used by SSRS, and ensure that it is running.

Another possible root cause is insufficient system resources such as CPU, memory, or disk space, leading to the service being unavailable. Check the system resources and make sure they are adequate for SSRS to function properly. Additionally, network connectivity issues or firewall restrictions can also result in the 503 error. Verify that the server has proper network connectivity and that any firewall settings are not blocking SSRS traffic.

Furthermore, corrupt SSRS configuration files or database issues can contribute to the error. You can try reconfiguring SSRS or restoring the configuration files from a backup to resolve this. Improperly configured or malfunctioning third-party software can also cause the 503 error. Review any recently installed software or updates and consider uninstalling or reconfiguring them.
