Can't wait 
Did you resolve this issue? If so can you please explain what you did, in simple terms. I am very new to coding. I have been hunting for a solution for ages. I can see my Octoprint login page in the HA webpage card, but stuck in a login loop. It cant seem to validate my login credentials. Thanks
The bug that I mentioned above was fixed in OctoPrint 1.7.0.
I am on 1.8.6. Hmm, i am back to square one. By anychance do you have any ideas what the problem could be, i just cant get past the log in page for Octoprint when embedded in HA.
bumping, but my guess is the issue is on the ha side
The original issue here was resolved 2 1/2 years ago. I'd probably open a new thread on the forums with the full details of what you're trying to do and what's not working - because the solution is obviously not the same as above.
