Tensorboard to remote server | UnimplementedError: File system scheme 'http' not implemented (file: 'http://<ip>:6969/train') [Op:CreateSummaryFileWriter]

I’ve a dedicated server always up and running, where I have started my tensorboard. And it’s already available. I’ve tested it on browser from a my personal laptop:

Now from my kaggle kernel, I’m trying to log there. Here is the piece of relavent code:

tensorboard_callback = TensorBoard(log_dir='http://<ip>:6969/')
 model.fit(xs,ys,
        ...
        callbacks=[tensorboard_callback]
)

But it throws an error:

UnimplementedError: File system scheme 'http' not implemented (file: 'http://<ip>:6969/train') [Op:CreateSummaryFileWriter]

How should I solve this issue?
