Trouble tracking down errors citing EOF and ast.Indent

Traefik Traefik v2 (latest)
,
1

I'm trying to setup pihole's webui behind traefik. The pihole service showed up in the dashboard when using traefik 2.1.1 but would time out when trying to access it. I switched to 2.6 and it doesn't show up in the dashboard at all. I'm getting the following errors.

level=error msg="Error matching constraints expression: 1:7: expected operand, found 'EOF'" providerName=docker container=pihole-stack-pihole-urbp3fjrr81xadi4groowyiui

and

level=error msg="Error matching constraints expression: unsupported *ast.Ident" container=pihole-stack-pihole-14dkor44cewvfeoahdieourr5 providerName=docker

I can't figure out where the indent or the EOF are coming from. I've tried changing the defaultRule and constraints settings but that didn't change anything in the way of errors. I also tried quite a few versions of the flags in the pihole compose. I assume I'm doing something wrong. Can anyone point me in the right direction?
Thanks

Hello @haxwithaxe

Could you please start the Traefik 2.6 without any additional services to figure what is the source of the error you are getting?

Traefik works fine on its own. It only shows those errors when I deploy the pihole stack.

Of course asking for help, waiting 3 days, and restarting them both again, the errors are gone. :confused:
It still doesn't work but I assume some RTFM will solve that.

Thanks.
