Synology dsm 7 cannot authenticate

Hi! I ve a synology with dsm 7, I ve just installed HA third package. I cannot connect to it, I tried the syno admin user… a homeassistant user, my own user… all of them have permissions to the HA app. The answer is always auth invalid… I tried to remove the .config folder… reboot the NAS several times… no way! :S some more idea? thanks!

What package did you install? Some of them have been removed from SynoCommunity store, while for other one I’m not sure if it supports DSM 7?
