Recently I’v seen another error, something like:
Your database behind back-end…

Please, help.
I installed federated node via docker. Interestingly, the main page is not displayed (*ttps://136.243.147.150/ 403 forbidden) and the src folder is displayed (*ttps://136.243.147.150/src/) Although in the manual it was stated that the main www needs to work, and in the src folder must placed minified files.
