[sa6kad]

Is this urgent?

No response

Host OS

Debian, Ubuntu

CPU arch

x86_64

VPN service provider

Custom

What are you using to run the container

docker-compose

What is the version of Gluetun

latest

What's the problem 🤔

First of all, thanks for a cool container!

I am using custom provider in order to connect to Ivacy VPN. Conf .conf files usually containd URLs of the VPN servers.

I tried to nslookup the IP address and substitute the URL and everything seem to work.
Other containers, such as dperson's do not have this issue.

It's explained in the wiki faq why that is, it's to avoid leaking anything before connection. So it's more by design than a bug, but I'm working on making this optional, subscribe to #788 for it.
