By Design, my OpenStack have 2 networks.

External Network (Floating IP) : 10.61.61.0/24
Management Network & Data Network (private): 10.60.60.0/24

An instance that deploys with floating IP cant access to the management
network. It is possible to change the URL from the error log (10.60.60.10)
to 10.61.61.10?

Best Regards,
Zufar Dhiyaulhaq
