I already reported this on github but apparently this forum is preferred, sorry for cross posting.
I'd like to report the same Issue.
Android App Version: 3.0.6
Mattermost Server Version: 3.0.3
The Mattermost server works flawlessly, but when connecting with the
Android App I also get "The address does not appear to be a Mattermost
server".
The request arrives at port 443 on the server but apparently nginx does
not receive a valid http request, since it does not log anything.
I can provide more Information if needed.
