It's odd that this isn't consistent, but sometimes I have issues adding movies from couch potato using nzb 360, nginx with ssl, and nzbget. Sometimes when I try, the url in nzbget has 2 problem:
1) It is http instead of https
2) It has the port number of 5075 added into the URL

If I take the url that shows up in nzbget and add an "s" to the http and delete the "5075", then the url works.

This seems like it could be an nzbhydra issue, but has anyone else had this problem or suggest a fix?
