cant access portainer

i guess portainer needs https now and trafeix checks http to see if site works but not https

For now, the workaround (thanks to @mrfret) is to downgrade to a lower version of Portainer that is known to work:

Revert portainer in PG/PTS:
sudo mkdir /opt/temp && sudo cp /opt/coreapps/apps/portainer.yml /opt/temp/
sudo nano /opt/temp/portainer.yml

change
portainer/portainer-ce:alpine

to
portainer/portainer-ce:2.16.2

then run:
sudo ansible-playbook /opt/temp/portainer.yml

I did this and all works until I redeploy Traefik. Once I do that it revers to the cd:alpine version. Any idea how I can stop it from reverting?
