caddy works in ipv4 OR ipv6 mode only

[nmr50]

1. Which version of Caddy are you using (caddy -version)?

Caddy 0.11.5 (non-commercial use only)

2. What are you trying to do?

I want caddy to listen to v4 AND v6 different resolved addresses at the same time as it was 2-3 weeks ago..

3. What is your Caddyfile?

http://v4.domain.tld:80, http://v6.domain.tld:80 {

#bind v4.domain.tld
#bind v6.domain.tld

root /home/tmh/caddy/web
gzip
log access.log
errors error.log

ipfilter / {
        rule allow
        blockpage def.html
        database /home/tmh/caddy/geolite/GeoLite2-Country.mmdb
        country RU UA LV EE IL US
}

gzip
gzip {
    level 6
    not   /images /videos
}
}

4. How did you run Caddy (give the full command and describe the execution environment)?

sudo batchfile
batch file content:

!/bin/sh

cd /home/tmh/caddy/
ulimit -n 8192
/home/tmh/caddy/caddy -conf caddyfile &
exit

6. What did you expect to see?

Two weeks ago I've running caddy old version (0.9.6 or something) - both v4 and v6 addresses worked well...v6 connections disappeared since then, and I re-installed caddy with fresh version mentioned earlier.

7. What did you see instead (give full error messages and/or log)?

The main problem that only v4 -- OR -- v6 addresses are working, not both of them at the same time.

8. Why is this a bug, and how do you think this should be fixed?

Don't know, really.

9. What are you doing to work around the problem in the meantime?

Still have no soliution, that is why I am issuing this problem...

10. Please link to any related issues, pull requests, and/or discussion.

So, when I use standard string http://v4.domain.tld:80, http://v6.domain.tld:80 - only v4 host is answering, so I see only v4 listening port:

netstat -nl | grep :80

tcp 0 0 0.0.0.0:80 0.0.0.0:* LISTEN

If I use bind for v4 AND v6 addresses, I see only v6 listening port:
tcp6 0 0 2001:..:80 :::* LISTEN 11107/caddy
If I comment out v6 bind string - I see again v4 listening port ONLY.

It still unclear - why v4 AND v6 started to ignore each other ?

I repeat - v4 and v6 addresses have different resolved names.

Bonus: What do you use Caddy for? Why did you choose Caddy?

Private homepage.

Thank you for the issue.

Can anyone else reproduce this?

Will probably be fixed in Caddy 2 as we've rearchitected the listener facilities.

This new 1.0.0 version I got from download server is working nice - both addresses - v4 AND v6 - are answering now. Many thanks ! :)

So — is Caddy no longer 100% open source?

[mholt]

@wmark Of course it is. Our source code license has never changed. This is very off topic, so please continue that discussion in our forums: https://caddy.community
