After Update from 13.0.3 the appstore is unavaiable.
I tried to connect to the url, which is logged (Timeout or 503) via curl:
Appstore 13.0.4
curl -I https://apps.nextcloud.com/api/v1/platform/13.0.4/apps.json
HTTP/1.1 503 Service Unavailable
…
Appstore 13.0.3
curl -I https://apps.nextcloud.com/api/v1/platform/13.0.3/apps.json
HTTP/1.1 200 OK
…
thank you in advance
