Sign up button does not lead to sign-up form
I have deployed commento using docker on an aws instance. Everything works well so far. Anonymously submitting comments works like a charm.
But as soon as a user wants to sign up by clicking the sign-up-button the entire page refreshes instead of getting redirected to the sign-up form. The same happens if the Rmarkdown button is pressed. I have tried Safari and Firefox on macOS.
What could possibly cause that?
Edit: It only happens, if the page is deployed via netlify. On my GitHub Pages site it works as intended.
