Upgrade does not work when using only IPv6 DNS servers
100%
Description
When only IPv6 DNS servers are used (in general config) GUI update is not functional.
Following message is displayed when checking for updates in the GUI:
Retrieving: Unable to check for updates.
Unfortunately I have not been able to find any logs of this.
running pfSense-upgrade from cli works fine.
Adding one IPV4 dns server, no matter which order will make the GUI check functional.

Seems to be fixed. On 22.01 if I set only IPv6 DNS and tell the GUI to only use remote DNS, the update check does fail.
Same setup on 22.05 works.

A couple of observations on this change, and the function in general. Firstly, there's a $nameservers variable being created by merging the hard coded test set with the system configured DNS servers, on line 2825 of system.inc. Either it should be iterated on in place of $gdns at line 2828, or it should be removed as useless code. Secondly, since almost all calls I could find to check_dnsavailable() do not pass any parameters, then the default for $proto should probably be 'any' and not 'inet', so that these checks still work on a system with only IPv6. Thirdly, it looks like on line 2833, the loop is limited to 3 iterations (ignoring the localhost skip), so the 4th entry of the 'any' array in the provided patch will never be used.
