Notes:

• Communication to Postgres is done exclusively over the private network and the database is not exposed externally in any way by default, if you want to enable access from outside of the private network you can go to the databases settings to enable TCP proxying and enter the internal port (5432) the TCP proxy can be again removed at any point to close off external access.

• Communication to Clickhouse is done exclusively over the private network and the database is not exposed externally in any way by default, if you want to enable access from outside of the private network you can go to the databases settings to generate a domain, the domain can be again removed at any point to close off external access.

I've identified an issue with the environment variables: the SMTPFROMADDRESS needs to be modified. For certain SMTP services, the SMTPFROMADDRESS differs from the SMTP_USERNAME. This problem has caused significant challenges, including the inability to register users post-deployment, compounded by the lack of useful error logs.

The SMTP_FROM_ADDRESS is set directly to the value of SMTP_USERNAME and I did not have issues with this using zoho, what email provider are you using and what format did you need to use for SMTP_FROM_ADDRESS?
