Web UI not opening

I recently migrated from 4.6.5-beta (simple-login/app) to v4.43.0 (simple-login/app-ci). All the emails are redirecting properly but I cannot access the UI via the browser and get 504 bad gateway error. I can't access the UI via the mobile app as well.

Upon inspecting the logs of the sl-app container, I keep getting this:

What seems to be the issue?
