Error: Inability to Connect to Mojang's API about 2faplus

I would definitely recommend switching from CraftBukkit/Spigot to Paper if you haven't: https://whypaper.emc.gs - this will fix your current issue at least.

I'll take another look at the (admittedly old) code running that particular lookup and see if I can optimize it or see what's going on. Thanks for the report!

Thanks!

This problem resulted from running the register command on a paper 641 instance connected to a waterfall network comprised of other paper instances and a single test spigot 1.8 instance.

I will try again with the outdated spigot instance disabled to see if it changes anything.

I must have skipped over the Paper 641 (1.13.2) somehow; this version of Paper SHOULD have the PlayerProfile API, I believe. In this case, it would be strange if it were still trying to use the BukkitPlayerInfo (rather than the PaperPlayerInfo) class. I'll have to take another look.

Thank you for looking in to it; sorry for my late response.

After two tests, I have concluded that this issue occurs exclusively in instances where one of the servers connected to the proxy (and/or the db?) is running a seriously outdated version (in this case, paper 443 (1.8.8)).

If it is possible to fix backwards compatibility for paper 443 (1.8.8), that would also be much appreciated -- I know that it is an absolutely terrible idea in general to use 1.8 versions but for my particular project, I have a relatively strong reason to use it for a singular instance).

Test 1
For the first test, I disabled all other servers connected to the proxy -- which represented all servers connected to 2fa+'s db -- and tested a single instance running 2fa+ 2.4.17 on paper 645 (1.13.2). During this test, I had no difficulties connecting to Mojang's API.

Note that I was still was unable to register new totp players using the plugin due to issue #5 .

Test 2
For the next test, I disabled all other servers connected to the proxy -- which represented all servers connected to 2fa+'s db -- and tested a single instance running 2fa+ 2.4.17 on paper 443 (1.8.8).
During this test, I received the error regarding connections to Mojang's db.
