Unable to access jupyter sagemath

edit

Hi, I am still new to the sagemath and learning. I have installed sagemath through ubuntu on a windows system. I was able to use the jupyter fine and do my codes. But recently, where ever I try to access the jupyter, It leads to the token authentication page and I do not know any token or password. I tried using the https token but it says invalid. Please help me access jupyter and resolve this issue.

Thank you
