Scrapping javascript website with Selenium where pages randomly fail to load

[Larz60+]

that's because the page does not exist!
look at the screens as they attempt to be brought up.
If you use the page internal links instead of set links you will avoid this error,
or you can:

• supply proper URL (one texted manually)
  
• just ignore missing data.
  

you cannot make a non-existant page appear, need proper URL
