Now I got it working 
Problem was docker container’s dns because my seafile server is inside corporate network and domain name doesn’t exist in public dns servers and by default docker container gets default google’s dns server 8.8.8.8.
So fix is provide internal dns server when installing oods to docker in such situations.
sudo docker run -dit -p 88:80 --dns=172.16.88.10 --restart always --name oods onlyoffice/documentserver
