Error with query log view behind swag/nginx proxy

Hello,
I have 2 pi-hole instant that since have upgraded to v6, I cannot navigate to the query log when using reverse proxy nginx/swag. When I do, I get a popup with this content:

image|452x270

Clicking on OK make it reappear in loop. It work well when I use only ip.

reverse proxy config:

## Version 2024/07/16

Thank you!

The update to v6 added an api, which can break existing nginx proxy config. Please try to add a new location: /api

sadly, same error :frowning:

Other users have confirmed this was the solution for them.

Please try a config similar to this: Can't get v6 webinterface behind nginx reverse proxy to work - #4 by stefan

I think I had a cache issue cause it started to work now. Weird. Thanks!

edit: in fact just remember, I had to removed the authelia part form the api
