503 on wildcard redirect

[tersor]

When creating a site with SSL wildcard, the wildcard http --> https is returning 503.

$ curl -Ik http://bar.example.com 
HTTP/1.1 301 Moved Permanently
Location: https://bar.example.com/

$ curl -Ik https://bar.example.com
HTTP/2 200 

$ curl -Ik https://foo.bar.example.com
HTTP/2 200 

$ curl -Ik http://foo.bar.example.com 
HTTP/1.1 503 Service Temporarily Unavailable

Is this to be expected?

@tersor I tried reproducing the issue but I couldn't. It's redirecting fine with me. @mbtamuli Can you try to reproduce it?

[tersor]

Ubuntu 18.04.1 LTS Easyengine 4.0.1

I created the site with:

ee site bar.example.com --type=html --ssl=le --wildcard

Altso, the /opt/easyengine/sites/bar.example.com/logs/nginx/error.log is empty.

[kirtangajjar]

@tersor you need to add DNS entries and then run ee site ssl bar.example.com after it.

Did you do it?

[tersor]

@kirtangajjar Yes, DNS entries added, and ee site ssl bar.example.com verified TXT records.

Altso, the wildcard subdomain responds with 200 OK, it is only the http redirect that returns 503.

[tersor]

I notice that I have this block in /opt/easyengine/services/nginx-proxy/conf.d/default.conf:

server {
    server_name _; # This is just an invalid value which will never trigger on a real hostname.
    listen 80;
    access_log /var/log/nginx/access.log vhost;
    return 503;
}

Probably from nginx proxy: https://github.com/EasyEngine/dockerfiles/blob/470ca0a61f971c8fea49adceb73a62605eadfbce/nginx-proxy/nginx.tmpl#L180

@kirtangajjar, do you have a similar config in your test?

[mrrobot47]

@tersor provide the output of more /opt/easyengine/services/nginx-proxy/conf.d/* | cat so that the redirections created by EasyEngine on your system can be diagnosed.

[tersor]

Ok, this is the only site on a clean server install.

ee site create leif.mediebruket.no --type=html --ssl=le --wildcard

It was deleted and recreated a couple of times (with the same create command). The domain got verified after the last create with ee site ssl leif.mediebruket.no.

[mbtamuli]

@tersor I get this. Proper 301 redirects and 200 OK response

[tersor]

@mbtamuli The issue occurs with anything other than www as prefix. For example:

$ curl -s -IL foo.leif.mediebruket.no | grep -Fi 'http'
HTTP/1.1 503 Service Temporarily Unavailable

[baitasite]

I have same problema :/

Error 521 Web server is down (but i use cloduflare)

Have solution?

[tersor]

@baitasite How do you conclude that this is the same problem?
