Link to reset password incorrect - http://default not resolved to URL

This issue is still unresolved. Can anyone advise me what to do?

Same here, on localhost working, but on staging enviroment no, I get the same http://default/...

Hello Guys again, I fixed this one.
Needed to add in settings.php the domain $base_url = "https://yourdomain.com";

For me this worked on staging and prod environment.
Hope this solve for you too, check and test it.

Do you have $settings['trusted_host_patterns'] set in settings.php? We do.
According to this article $base_url was ‘removed’ from settings.php for better security in favour of $settings['trusted_host_patterns'].
There is an inconsistency that needs investigating if this is the case and the Password Policy module still needs the global variable $base_url

Yes, I have this too.. everything is fine.
Only on this Password Policy module got problems with the link from mail..
I only added the $base_url in settings.local.php which is included in settings.php and solved.
So.. yes, maybe the module still need this global variable.

Was the email sent as a during the running of the cron functionality?
If so perhaps further investigation is needed there to see if drush cron is being passed the correct parameters. See https://www.drush.org/12.x/commands/core_cron/ for more information on this.

Emails are sent via cron, when using drush you need to make sure drush uses your site's url with the --uri flag, or set the DRUSH_OPTIONS_URI environment variable.
