I run erpnext via:

cd /home/erpnext/erpnext
./lib/enf.py --serve

I connect to servername:8000 and get the following error with traceback call:

This means that erpnext is not able to access mysql with the dbname,
username (same as dbname) and password in conf.py.

The server ran fine several days ago, but this error came up - unable to
proceed.

erpnext

Pratik,

Thank you for the reply.

I understand this MySQL error 1045 is an authentication error for the database  I am curious as to why this is happening and what we can do to fix it.

In CONF.PY under /home/erpnext/erpnext/
the # database config is as follows:
db_name =  '%(db_name)s'
db_password = '%(db_password)s'


Am I correct in assuming the user should be parsed, instead of read as a user named "%(db_name)s" ? If so , what would make this function incorrectly as such ?

Your conf.py did not get created correctly. the %(db_name)s should be replaced by the name you gave at time of install....

You can try again or fix conf.py with the correct credentials.

If you are following this https://pipech.github.io/erpnext-docker-debian/development_setup/ one can reproduce the issue easily. It is so annoying , even changing the credentials on the Mariadb container doesnt seem to solve the problem.
