Host connection blocked by docker0

Hello, I’m new on this docker world. I’m using docker-ce on ubuntu 17 and something really strange is happening to me. Everytime docker service is startet and docker0 connection is created my host is unable to access internet. I have to manually delete docker0 so I can get internet connection again. After doing that my docker applications are unable to access internet and to start my applications I have to restart docker service. When I do it, applications work fine but again the host can’t access internet anymore. This is very annoying, is there any solution for that? Thanks in advance.
