Addendum:

In my case the URL triggering the Error https://<your_site_url>/mailman3/accounts/fedora/login/?process=login&next=%2Fmailman3%2Faccounts%2Fsignup%2F is returned by:

• https://<your_site_url>/mailman3/accounts/signup/?next=%2Fmailman3%2Faccounts%2Fsignup%2F

[...]

<div class="socialaccount_ballot">

  <ul class="socialaccount_providers list-inline">
