What is the problem?
The login via haproxy is always rejected.
What did you already try to solve it?
Tried login in via the url with port 5000. That works.
Tried rebooting the pi.
serial.log or output on terminal tab at a minimum, browser error console if UI issue ... no logs, no support!)
Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ... as much data as possible)
Octopi on raspberry pi 4. Configured to run 2 instances. If connecting to port 5000 or 5001 I get a login and am able to login. When I use the /a10/ path I also get the same login but it does not work.
I tried enabling http authentication on haproxy. That only adds a http login but when logging in it still stops at the regular login.
