Thanks a lot for ur assistance man - I really appreciate it !
i couldn't solve it , my server probably marked by some attackers as in the second i start it i got hundred of calls from unknown addresses.
I decided to change domain so i bought new domain and register it to CF,
hopefully this will make it safer.
I open new post for traefik+ CL:
(Although it very interesting to know what was wrong in this setup)
