Hi there, @tfrankjeep 👋
It sounds like you may need to run through these troubleshooting steps with your Square Reader for contactless and chip. You can get started by heading to that page, but if you need a hand or aren't able to get where you need to be, our Support team would be able to look into this for you!
If you need to reach out directly, please log into your Square account and head here.
I'm not sure what you mean to ask about you domain name, but your domain name should not affect your ability to process payments using your Square contactless and chip reader.
