What is the problem?
I get page refused to connect when trying to display the OctoPrint page in a Home Assistant tab (iframe)
What did you already try to solve it?
Tried both octopi.local and the IP address.
Have you tried running in safe mode and if so did it solve the issue?
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.)
This does not get logged as it comes from home assistant
Additional information about your setup
OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible
Home Assistant 0.116
