[MM3-users] ERROR sqlalchemy.exc.OperationalError: (psycopg2.OperationalError) could not translate host name xxxx to address

Hi! The error above occurs when starting mailman. The xxxx shows a part from the database section of mailman.cfg. I followed the tutorial https://wiki.list.org/DOC/Howto_Install_Mailman3_On_Debian10. But since django and postgres changed some things, I had to fix some files of mailman3 to get it working.

This is the part of mailman.cfg: [database] class: mailman.database.postgresql.PostgreSQLDatabase url: postgresql://mailman:<mypassword>@localhost/mailman Full error: sqlalchemy.exc.OperationalError: (psycopg2.OperationalError) could not translate host name "assword>@localhost" to address: Name or service not known

How can I fix this? Thank you very much for your help.

Regards,
