what os did you try with? what steps or tutorial did you follow docker / bench / ova ?? where did you try to install it like aws or digital ocean or on your machine ?
I am sorry for the troubles you are having. I was also struggling with the installation of ERPNext for a couple of days before I went with the Docker install following these instructions:
With this I was able to install it with no problems all the times for all the tests that I had to do.
I was resisting to go with Docker for years but it is not so horribly difficult as it seems, although I am only at 0,2% of it.
Althought it is not all perfect with this. App installation seems to be a nightmare, and I am still trying to find if it is possible to switch from develop to stable in docker version. But I am afraid it wont be possible.
The message you’re receiving “Sorry, we will be back soon” just means the site is in “maintenance mode” just run bench set-maintenance-mode off also, run bench restart to make sure all services are running.
