Cannot access docker container which located on server via server ip

Question

So, i have server with docker installed in it. I run docker containers on 0.0.0.0:80:80: If i run

curl -X GET 0.0.0.0:80

i'll get some response, but if i run

curl -X GET 195.161.68.88:80 

i'll get nothing ( 195.161.68.88 is server ip)

i thought container has no internet connection, but

ping google.com

inside of a container works properly, 0% packet loss

also if i run clear django project on server(not inside docker) on ip 0.0.0.0:80 it can be accessed by both curl examples above

any ideas why i cannot access docker containers via internet by server ip?
