SBCE 7.2.1
nginx restarting
· Restarting nginx-data alarm, Remote worker endpoints unable to register and SSYNDI Crashed.
· SBCE 1 status DOWN and SBCE 2 UP
· Both nginx-data.service failed to start
1. Restarting Nginx-data
The below error was seen during restart nginx-data.
It seemed stuck to initialize RW_PPM_1 with user nginx. I checked the files but I did not find anything wrong so I removed all Reverse Proxy configurations

2. HA status: 10.1.2.3 was Primary and 10.4.5.6 was DOWN
Both 10.1.2.3 and 10.4.5.6 were not working properly. 10.1.2.3 was changed to DOWN when I tried to restart ‘ipcs-init’ to bring 10.4.5.6 back. Also found found ‘Ssyndi’ was not up on both servers.
3. Re-configured Reverse Proxy flows
Re-configured Reverse Proxy flows: RW_PPM_1, RW_PPM_2 and settings but there were four items missing that could not see the complete names of url from the screenshot.
