I am using Sitecore 9.3 with SPS 4.2. Publish is working fine but "Publish Related Items" is not working. After digging into some documents and Sitecore Support I came to know that I need to change the Links databases into SPS configuration Core to Web.
I made the change and after that I am continuously getting errors -
In browser console I can see - /sitecore/api/ssc/publishing/maintenance/0/IsRunning - Response status code does not indicate success: 502 (Bad Gateway).
And on Publish window and Publishing Dashboard getting - Publishing Service not working Contact Administrator.
I am changing back to Core it again start working but Publish Related Items not working in this case.
Anyone faced any similar issue with SPS? Any help would be appreciated.
