On the clearing of tensorboard history + running of tensorboard after killing it

Hi all,

2 questions from me regarding tensorboard:
1)
I previously got tensorboard to run but after killing it via the windows command prompt, am unable to restart it again. How can I restart it successfully without running into ’ localhost refused to connect./
2)
Also, would like to delete history on tensorboard. I understand from some forums the directory has to be deleted + process killed. Not too sure how the former works, would appreciate any advice on this.
Where can I find the directory? Within the tensorboard package in windows explorer?

Thanks

An update for anyone who might find themselves with the same problem:

I decided to end my misery over tensorboard and have switched allegiance to visdom - it’s been an absolute breeze.

Linking a very useful github which helped me quickly set up visdom for the plotting of accuracy and loss graphs:
