Some or all of the below information will be requested if it isn’t supplied; for fastest response please provide as much as you can :heart:

Nextcloud version (eg, 29.0.5): 30.0.1.2
Operating system and version (eg, Ubuntu 24.04): Arch (latest)
Apache or nginx version (eg, Apache 2.4.25): Apache/2.4.62
PHP version (eg, 8.3): PHP 8.3.13 (cli) (built: Oct 23 2024 07:04:22) (NTS)

The issue you are facing:

After updating to 30.0.1.2 I can’t make any request to Nextcloud when accessing it through LAN with ipv6 when using link-local address: it causes ArgumentException: Given IP address can’t be parsed. For example, it is accessible via http://localhost, but via http://my-host.local it breaks with error.

Address was fe80::1fc4:15d8:78db:2319%enp4s0. Seems that interface suffix (%enp4s0) causes this error.

There was no such issue before (I don’t remember what version I had before, maybe 29.0.8.1, according to previous entries in updater.log)

Is this the first time you’ve seen this error? (Y/N): Y

Steps to replicate it:

  1. Update to 30.0.1.2 with web-based updater.
  2. Open Nextcloud web UI from address that causes it to be requested from link-local ipv6 address

Hi,

after updating to Nextcloud 30.0.1.2 my log was also flooded with the same error message …

After investigating this error I’ve found out that the problem seems to be the network interface (everything after %-sign) of IPv6. The IP-Lib library probably has parsing problems with IPv6 if it contains network interfaces.

As a workaround I’m currently removing the network interface before parsing address string.

In file lib/private/Security/Ip/Address.php replace line 24 containing
$ip = Factory::parseAddressString($ip);
with the following line of code
$ip = Factory::parseAddressString(preg_replace('~%.*$~', '', $ip));

This will remove all network interfaces at the end of string and so IP-Lib is happy …
Hope this helps :slight_smile:

Fix pending in fix(net/security): Handle IPv6 zone IDs in link-local addresses by joshtrichards · Pull Request #49039 · nextcloud/server · GitHub.

If you’re able, test the more extensive change in that PR. Keep in mind it’s fresh and un-merged so further changes may be made.

I’m surprised this hasn’t been reported before, though it does only impact link-local addresses.

Feel free to try this: https://github.com/nextcloud/server/pull/49038

Should work and use iplib as designed.

Applied patch from PR 49038 (seems that 49039 has the same changes) to my local install and it works.

Hah. Indeed. @MartB and I seem to have both submitted a fix within minutes of each other.
