Need Help With Eufy Security Integration

So I have a SoloCam S40 and and trying t install the HACS Eufy Security Integration.

I’m following the documentation.

http://homeassistant.local:8123/hacs/repository/380367845

When I get to the bit to enter Eufy Security add on IP address I follow the instructions in step 5 of the documentation

5- Put Eufy Security Add-on IP Address (127.0.0.1 for Supervised installation) and configured port (default 3000) and click Submit.

However when I click submit I just get an error that the port/IP is wrong.

Anyone have ay ideas what I’m doing wrong?
