Like many who self-host their Owncloud servers, my ISP blocks traffic on ports 80 and 443. As a result, I have to use a non-standard port for access to my Owncloud server. Enpass doesn't seem to support specifying a port in the URL for the Owncloud server. When I try I just get authentication errors. Please add this feature.
