Hi,

Please check your Odoo logs to get more details on the issue you're facing. Additionally, try changing the HTTP port in your Odoo configuration file

Hope it helps

Hello, 

Kindly review your odoo config file. If you mention the db_user and db_password. 

In that case, alter the Postgres user password.

Use the following commands:

• su postgres 
• psql 
• ALTER USER user_name WITH PASSWORD 'new_password';

Or 

If you're facing other issues in that case kindly review your odoo log file.

Thanks
