Has this been happening to anyone else when trying to connect to the GTS? Is Pokèclassic Network down or is it just an issue on my end?

i play through MelonDS. for some reason, mystey gift works perfectly fine, but the gts does not. i tried readjusting the settings, alongside erasing the connection and adding the dns again to make sure i had the right ones. the bios also correct as far as i'm aware.

the second also appears when starting up the gts. should i be concerned?
