I have after a lot of work managed to install ee4, letsencrypt and wordpress on my domain: psykolog.nu.
Everything seems to work expect the fact that http://www.psykolog.nu generates 503 error. I guess this has to do with some configuration of the nginx proxy?
According to http://redirectcheck.com/index.php http://www.psykolog.nu generates 503 Error , however if I curl -v http://www.psykolog.nu it shows 301 (as it should).
How shoudl I fix this? Very annoying.
