Lately I think have more issue to get portainer working, even if I uninstall docker reinstall them I try to do the same for portainer no matter what I am landing on the the site can not be reached,
by the way since the last version of omv5 in the pop up window we can not see as before if something getting wrong or not it just says install or uninstall anyway right now my only work around is to run
Code
docker run -d -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data portainer/portainer
basically after each reboot?
