After I finally got wkhtmltopdf to work properly (setting report.url to "http://127.0.0.1:8069" did the job)

Now I have the same problem as before again when I add a dbfilter. 

The dbfilter I use is:--db-filter=^%d$ 

The moment I try to print a report I get the following warnings in the logging:

WARNING odoo.http: Logged into database 'test', but dbfilter rejects it; logging session out.

WARNING test odoo.addons.base.models.ir_actions_report: wkhtmltopdf: b'Exit with code 1 due to network error: ContentNotFoundError\n'

Also the layout of the report is not ok, just like when the system parameters were not set properly. 

could this be a problem with the nginx settings? or is this an odoo problem?

(wkhtmltopdf is 0.12.6 on debian 11)

Thanks in advance for the help with this.

Update: 

When I do a logging of the http request (in http.py) I always get http://test/  unless I print the report, then I get localhost:8069. And that is probably when the db-filter kicks in... So this is probably the cause. Now just find the solution :-)
