Different port. Grafana is on port 9000 and is at http://grafana.bsmt-srv1.home.arpa:9000
PyPowerwall is on port http://grafana.bsmt-srv1.home.arpa:8675
What appears to be working is traefik appears to be proxying http://grafana.bsmt-srv1.home.arpa:9000 to https://grafana.bsmt-srv1.home.arpa:443 correctly.
The problem appears to be that the frame is still at http://grafana.bsmt-srv1.home.arpa:8675 and is not being proxied. Even though I have those labels set it wants to look at https://grafana.bsmt-srv1.home.arpa:8675 for it, which does not exist hence the error.
Everything only works when I disable TLS on the grafana docker container and serve the whole page over http, something I want to avoid doing.
Thanks in advance 
for helping me worth through this, I have been pulling my hair out over this for some time and was never able to solve it myself.
