I have just migrated from 1.6.0 to 1.7.4. Upon migration I can log in but then get this screen. I also get this error in docker. Don't know if anyone has any idea on how to fix this?
TL;DR
Developer migrated from 1.6.0 to 1.7.4, can log in but gets "must be a valid domain or hostname" error on screen. The issue is also showing up in Docker. Any suggestions on how to resolve this?
