Windows 10 PC Octoprint Log in fails

What is the problem?
If I log into Octoprint via my iPad and then log out, I cannot log into Octoprint from my desktop PC. Both machines are on my home network. I can log into the Pi via putty and I can log into Octoprint with the iPad through The iPad atuo logs in with the correct password. If I log out from iPad I still cannot connect through the PC
What did you already try to solve it?
reset password.
Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, octoprint.log, serial.log or output on terminal tab, ...)

Can you connect to RasPi with OctoPrint on it via SSH (with PuTTY)?

Having the same problem. Was working fine one night and the next morning, I could not login..

Sometimes routers do a firmware update over night and restart. You maybe got a new IP for the RasPi/OctoPrint?
