AttributeError: 'NoneType' object has no attribute 'replace'

```
# python3 rbtv-dl.py https://www.redbull.com/gb-en/episodes/wide-boyz-reel-rock-s01-e05
Traceback (most recent call last):
  File "rbtv-dl.py", line 55, in <module>
    title = title.replace(char,'-')
AttributeError: 'NoneType' object has no attribute 'replace'
```

This is what I get. Assume it can't get the html if I can't even extract the title.
