I bought the NextCloud VM for Hyper-V from Hanssonit.
But I can’t login after the first start.
The first start ends in a login.
I trie’d the credentials user: ncadmin, pass: nextcloud but it doesn’t work.
you can either manually edit in your DB or add the file CAN_INSTALL to your rootdir. this should prompt you with the wizard, where you can reconfigure your installation.
Are we talking about login to the webgui or login to the console/ssh interface?
I do not know hanssonit, but your provider must either give you this information or he has given it to you and you missed it in the (assumed) documentation.
