CHT Upgrade failing in docker helper 4.x

[sugat009]

Describe the bug

I tried upgrading a 4.x CHT docker helper instance of CHT version 4.6.0 to 4.9.0 and the upgrade failed. The browser shows the 502 Bad Gateway page whereas the containers have been stopped if you look into the terminal.

To Reproduce

Steps to reproduce the behavior:

1. Start a CHT docker helper 4.x instance
2. Start the upgrade
3. Reload page
4. Check docker containers

Environment

• Instance: CHT docker helper 4.x
• Browser: Firefox
• Client platform: Linux
• App: N/A
• Version: 4.6.0
