Longtime user (since 2010 ish), first time poster. I think I've reached out on Github before though.
I set up a new Octoprint instance (via OctoPi the image: version 1.10.3) for another printer and the "Remember Me" checkbox was not working on multiple computers. I did some searching and found that every so often there's the same problem from a user perspective, albeit a different problem in the code. I found ~6 different occurrences over the years, but nothing current on the net (forum, reddit, etc) nor Github.
Today I tried using the .local name to connect, instead of just the hostname. It's been a few hours (not much time to tell if it worked), and so far it's worked.
Is there a known issue in this version of Octoprint?
I have the hostname(s) whitelisted in NoScript, and the cookies allowed via Cookie AutoDelete, which works fine with the other 3 printers I have OctoPrint running on, and this has worked for many years. I use Waterfox, and browsers on these computers are setup similarly, and only this one instance of Octoprint has an issue.
I am in the process of setting up 3 new instances, and will be re-imaging 2 more, and would rather not use a version with this issue in it if I could help it.
