Can not duplicate server

We want to duplicate our server, in order to achieve a staging environment where we can do extreme tests.

I followed this tutorial to change the IP address of the server. Additionally to the tutorial, I added the following steps to change the external URL:

bm.ini: external_url changed
postgresql: adjusted the second command to include external url:

sudo -u postgres -i psql -h localhost -U bj -d bj -W -c "update t_systemconf set configuration = configuration || hstore('host','<new IP>') || hstore('hz-member-address', '<new IP>') || hstore('external-url','<new external URL>');"

When I then start the server again, I get this Keycloak error:

If I press on “Back to Application” I get redirected to the production server.

The keycloak part was missing. Managed to do it in the end with external help.
