no certificates after container build

Hello,
I was using your caddy container 1.0.0 for month till my server broke down. it took me some time to buy a new one. I set it today with the old Caddyfile.
Logs are showing ow this lines in a loop and I am without any idea after googling for hours

```
Activating privacy features... 2019/06/23 10:03:11 [INFO][cache:0xc0000b7090] Started certificate maintenance routine
2019/06/23 10:03:12 [INFO] acme: Registering account for mymail@yahoo.de
2019/06/23 10:03:27 registration error: Post https://acme-v02.api.letsencrypt.org/acme/new-acct: net/http: timeout awaiting response headers
exit status 1
```

this is my container command:
``````

docker run -d\
--name caddy \
--restart=always \
-v /docker/config/caddyneu/Caddyfile:/etc/Caddyfile \
-v /docker/config/caddyneu/log:/etc/log \
-v /docker/config/caddyneu/.caddy:/root/.caddy \
-v /docker/data/caddy/www/:/srv \
-p 80:80 \
-p 443:443 \
-p 2015:2015 \
-e ACME_AGREE=true \
abiosoft/caddy:php
```

and this is my Caddyfile config:
