In an attempt to repair a broken SSRS installation for Operations Manager, I have attempted a fresh install using SQL Reporting Services 2017 (14.0.600.1669). When running OM 2019 RTM Report Server (Setup version 10.19.10050.0) it changes the SRS extension in the rsreportserver.config, the ReportServer web service stops working with 503 error. Other discussions I have seen with similar issue suggested a newer version of SSRS (done) and others suggest turning off AV (done) and I am still seeing this issue.
Does anyone else know how to troubleshoot why the OM Extension would be giving the ReportServer a 503 error? I am wondering if some other aspect of the server hardening could be impacting it?
