iPad connects, logs in, but no interface or error messages

What is the problem?

iPad connects via wifi, I am able to to connect to octoprint, login, password all work fine, but octoprint UI never shows up on browser. No errors.

What did you already try to solve it?

I have ssh'd into my octoprint, tailed "tail -f ~/.octoprint/logs/octoprint.log" # I can see all events that are being logged just fine. no user interface errors. It shows when my ipad logs in, no errors.
I added DEBUG to logging for environment, access, server and octoprint. Restarted octoprint.
set up tail on log (above) and attempted connection from ipad. Again, connection works, get login prompt, enter user and password, it logs in, I can see it in the logs, but nothing of the interface shows up except in the browser tab the title changes to "octoprint" as it should.

Have you tried running in safe mode?

No.

Did running in safe mode solve the problem?

N/A

Complete Logs

I tried to put in complete log, it would not allow me to do so, so I had to put in excerpt. Did not see a method to attach a log file.

octoprint.log, serial.log or output on terminal tab at a minimum, browser error console if UI issue ... no logs, no support! Not log excerpts, complete logs.)

iPad is up tod ate as much as it will allow. It's a gen 2 I think. And that may be the issue.

Yeah, this is slated to be fixed in the next release of OctoPrint based on this issue.

Awesome. Thanks for the feedback.
