Done this and go the following reply:
Thank you for contacting support. We are not blocking the queries on our side and you will want to try using our DNS servers if the public server you are using do not work:
Primary: 198.18.0.1
Secondary: 198.18.0.2
Didnt make any difference for me.
Im also getting this (if the docker is restarted). The only way Ive been able to fix it is to recreate the docker each time.
I was originally using Newshosting but they are now also Privado
