What is the problem?
I can SSH in but am unable to login via a browser.
What did you already try to solve it?
I followed the suggestions at the help page I forgot my OctoPrint password, how can I reset it? and deleted the users.yaml file and then restarted the service. I emptied my browser cache, set the config.yaml file to firstrun: to true and when I go to the ip address, it still asks me for a login. I tried another brower as well. I inspected the users.yaml file and found my username but no passwords that I know of work. I would have thought on the deletion of the users.yaml file and restarting the service, this login request would have gone away.
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.)
