OctoPrint.local wont let me login

What is the problem?

I have been using octoprint for a while and I keep on running into this problem, when I install octoprint on my printer I create my account and it works perfect for a thew weeks but, every time after a thew weeks octoprint.local wont accept my login information anymore, the only way that I have found that works to resolve the problem is to reinstall octoprint every time, it is starting to get very annoying to reinstall it every time, is there any one that may know why my octoprint is saying that my login information is incorrect.

What did you already try to solve it?

I did try to change my login information but it didn't work.
