Phew. It is done. Level0 is now HTTPS-enabled with OAuth2 support, working on a new fast server. All thanks to npub1927us0g736685d62s5pkt3ayma7q3u4mf0dgsv5gfzlgc2qrtfjse78a3c (npub1927…8a3c) support that made me speed up my php coding and ansible scripting.
Enjoy! https://level0.osmz.ru/
(My others services are migrating too, e.g. the imagery offset database.)
