Normally this is caused by the container trying to resolve an IPv6 address for api.temoviedb.org. To verify if this is the issue:
docker exec -it petio sh
nslookup api.themoviedb.org
To fix this issue, go back to when you first configured Docker and remember if you made some custom changes. This is not a Petio issue but rather an issue on your configuration.
