What is my xweb wsdl url?

I thought I had the right information. I’m using this url:

https://member.thedma.org/xweb/

but, when I try to log into wordpress with my Avectra creds I get:

https://prntscr.com/8lyl2m

Is the error due to the wrong url in the configuration of the plugin or my credentials?

Thanks.
