Sometimes it is required to access the database from different URLs. To avoid every admin URL changing web.base.url parameter, please add another parameter web.base.url.freeze with value "1"

Do you mean parameter web.base.url in Setting -> Parameters -> System Parameter?

IMHO is loaded by local doamin name but, peraphs, you should update it.

Hi,
We can change web.base.url value form settings->Technical->system parameters->web.base.url

Otherwise,

Using the Odoo Configuration File:

If you have access to the Odoo server and configuration files, you can modify the web.base.url in the Odoo configuration file. Here's how:

a. Locate your Odoo configuration file. It's typically named odoo.conf or similar and is often found in the Odoo server's installation directory or in a specified configuration folder.

b. Open the configuration file using a text editor.

c. Search for the line that specifies the web.base.url parameter. It should look like this:

web.base.url = http://example.com:8069

d. Update the URL to the desired base URL for your Odoo instance.

e. Save the configuration file.

f. Restart the Odoo server for the changes to take effect. You can do this using a command like:

odoo-bin -c /path/to/odoo.conf

Hope it helps

In Odoo 16;

1. Enable Developer mode first
2. Settings > Technical > Parameters>System Parameters
3. Edit Key web.base.url
4. Change value and save

The Settings->Parameters->System Parameters menu is hidden by default.

First enable the Technical Features for your admin account in the Settings → Users → Users → Administrator → Access Right
