If your internet uses IPv6 to try to connect to the minetest server, the connection fails. It doesn't help that linuxgaming2.com has an AAAA DNS entry. You can connect by manually entering the IPv4 address of the server. I'm not sure if the minetest server on LG2 is configured for IPv6 or if minetest in general can't support it, but there's something about it that keeps the connection from working properly.
The AAAA DNS... I hadn't given it much thought. My guess is it was just part of the deal when I bought the domain name. (Info tidbit for others reading this who may not know: "AAAA DNS" is for the, somewhat newer, IPv6 Internet protocol and "A DNS" is for older, standard IPv4 Internet protocol.)
As for LinuxGaming's Minetest server's IPv6 setting, that has been disabled for a couple years now for a few reasons.
1. From what I've read and experienced over the years, Minetest's network code is not so good. It has improved, here and there, but still needs more development and refinement. I disabled the IPv6 for the Minetest server, figuring it would be one less thing for Minetest to fumble and lag while trying to handle or one less thing to contribute to a crash. I realize this means players who use IPv6 exclusively will not be able to connect to LinuxGaming's Minetest server and I'm OK with that. I'd much rather error on the side of caution and have LG continue to be fairly stable, as it has proven to be through the years.
2. LinuxGaming's physical server is located in the US. The US still uses IPv4, predominantly. My thinking is that there will be far more IPv4 junctions than IPv6 junctions available for Minetest clients to pass through, thus increasing their chances of getting on a stable connection.
3. A few years ago I checked into IPv6 and found that it was not used, relatively, as much as IPv4. When I researched it again today, the heavy majority of the balance is still on the IPv4 side; not only in the US but globally as a whole. IPv6 has been in development for the past 30 years and *still* is far in the minority; I doubt that the balance will shift for many more years to come. This leads me to believe it is quite likely that there are more Minetest players using IPv4 than IPv6.
Considering the stuff above, it seems prudent to stick with just IPv4 for now.
