🐛 [Bug]: system reachable via ICMP and via Port 8008 but screen "navy blue" with no text whatsoever

[JuniperChris929]

Bug description

I start serge (docker) in an IPv6-only environment
The page loads - the background changes to the usual "navy blue" but nothing on the page actually shows up despite the website signalling me, that it has successfully loaded

Steps to reproduce

pull the latest docker container
start serge with IPv6 enabled
access the web.ui via IPv6

Environment Information

Docker version 20.10.18, build b40c2f6
Client accessing: Windows 11
Browser accessing: latest Chrome and Firefox (same behavior)

Screenshots

No response

Relevant log output

No response

Confirmations

• I'm running the latest version of the main branch.
• I checked existing issues to see if this has already been described.

@Smartappli Any ideas?

[JuniperChris929]

Happy to provide more info if needed.

[gaby]

@JuniperChris929 Does it work from localhost?

[JuniperChris929]

Yes - If I run the very same docker container on one of my Linux-Laptops it works fine.
But as soon as I run this on a server and access it from "outside" I'm greeted with this behavior.

Already checked everything firewall-related - all green. I can see the traffic hitting the container and can also see the answer-packets.

The weird thing is, that it loads the favicon (the little llama) and seems to load the page but somehow never finishes for some weird reason

[JuniperChris929]

Apologies - I tested too quickly ;)
The Laptops run Dual-Stack - so they serve the page over IPv4.
If I "force" IPv6 they also show this weird behavior.

[JuniperChris929]

Do you need anything from my side?

[JuniperChris929]

just saw that you implemented some fixes for IPv6 in the last commit(s) - will you release a new Version soon so that I can test of this fixes it? If I pull the "latest" tag from docker - does that already include the latest commits or is this just the latest released version?

[JuniperChris929]

any news regarding this fix? Can we expect a new version soon? :)

[JuniperChris929]

Any updates when a new version can be expected? It's been 4 months now and you probably already fixed a lot of issues

[gaby]

@JuniperChris929 Does this happen with ghcr.io/serge-char/serge:main ?

[JuniperChris929]

Yes - same behavior (once I say IPv4 = false and IPv6 = true in serge.env
