i have also same issue can you suggest me how to solve this error

The error is still there after so many months. But at least, they now have a few reasons why it may not work. Nevertheless, it is not satisfying not to be able to create a free trial database. How can customers trust that it works for them, if they already have issues creating a database?

Hello,

If you are using your private server then make sure, you didn't set the dbfilter inside your odoo config file.

Thanks,

I  made it. Iphone + Safari + Incognito Mode + Mobile Data

don't ask me why but it worked

Try with your phone (just the creation part).

I don't know exactly why this works but it does seem to be a solution for many people with this issue.
