actually this works.
don´t know why it didn´t before, but right now that´s how i do it.
- Snap of Prod.
- Rebuild Dev from Prod Snap
- change app.ylm “DISCOURSE_HOSTNAME” to new DevAdr
- Rebuild App
you should not do this to often in a week, as there is a rate limit for ssl trusted certificates. Best practise:
snap Prod, rebuild Dev, Snap Dev
Every Rebuild on same Address, dosn´t lead to new creation of ssl certificate.
This is the easy way for me to create a test server, just a few clicks.
