Hello, I have bought a custom domain and set up CNAME following your guide, alias WWW, points to webapp-xxx.pythonanywhere.com, and it works!
But only works when I enter www.domain.com in the browser, not with domain.com (without the WWW). So far my domain provider asked me to create an A record, alias @ and point it to the IPV4, but I've read your IPs could change pretty frequently.
I've tried to: Create a CNAME with alias @ and point it to webapp-xxx.pythonanywhere.com, no result. Create a CNAME with alias domain.com and point it to webapp-xxx.pythonanywhere.com, no result.
What else would you recommend me to try? I know that's not a problem you can fix, but maybe I am missing something pretty simple.
Edit: I also got it with Let's Encrypt certificate, and it works!
