Running into this issue when I try to connect
I find this type of problem reporting really offensive. Spend at least 2 minutes opening the ownCloud in a different browser. Check your admin interface, ssh and logs and fill out the template is already there asking you all the questions.
This is a public warning, if I see another post like that from you, I’ll silence you for two weeks.
EDIT: I apologize for the harsh wording, I’ve toned it down a little. That was uncalled for, I’m sorry must have gotten up on the wrong foot this morning.
