I upgraded AA Control Room 360 and IQ Bot 360 to latest version but I get the" bad gateway" error on both URLs,

I tried to troubleshoot according to suggestions in:

• Apeople :https://apeople.automationanywhere.com/s/question/0D56F00007jtFP2SAM/in-control-room-it-is-showing-bad-gateway-even-after-restarting-the-services
• https://apeople.automationanywhere.com/s/article/A2019-Control-room-Not-accessible-after-Installation-502-Bad-Gateway

but the problem is still occurring and services are down.

troubleshoot steps which I performed

1. Services are started and using AD accounts
2. SQL is accessible 
3. Health Check URL (http://localhost:8100/healthcheck) shows services are be ok

Would you please help me with this?
