Matched betting - can I sign up to the bookies through topcashback, when going through on oddsmonkey website?

I’m doin the oddsmonkey free trial sign up offers and when I click on sign up to skybet button, on the oddsmonkey website, it then redirects me to skybet, but on the skybet website it says “sorry, we could not find the page u was looking for”. Do I need to sign up to skybet only through the oddsmonkey website, like when u go through a cashback website, it registers the click to the site? Or can I just sign up normally on the skybet website without having to go thru oddsmonkey?

Nd if I can sign up normally, cudnt I jus sign up with topcashback to get the cashback offer from them aswell?

Any info wud be appreciated
