SendingFailed Triggered When Sending My Website Link Only

I am using Zapier for this API integration. When I try to send a test message to my phone with a link to the scheduling page on my website, I get the SendingFailed status. 

However, when I use various test links such as google.com, amazon.com, or even a small local company in my city like https://bendbeautyspa.com/ the test message always goes through. Is there something I’m missing? 

I’ve sent text messages with links to my website in the past but now this error code appears.
