Cannot convert Westjet Rewards to Telus Rewards after changing password

I have both the Westjet Rewards and Telus Rewards and have linked the accounts ever since it was available. 

I had to change the password of my Telus Rewards account recently.

Now when I try to convert my Westjet points to Telus Rewards, I’m being asked to sign in to my Telus account - and once signed in, it says the page cannot be found. I tried using the app, the web browser on my phone, and the web browser on my computer - all with the same result. 

I checked and my accounts are still linked to each other, but I keep being asked to sign in. 

I do not want to unlink then link my Telus account as it will remove my perks.
