Unable to connect to Ultimate Reloaded

[Demento56]

I can get to the Craftersland hub world - the one with the compass where you select a modpack - but whenever I try to connect to Ultimate Reloaded my client freezes up for a few seconds and then I get Connection Lost Disconnected. I haven't had this happen before 4pm or so today. I am on version 1.12.2 and my username is Demento56. Any ideas?

Update: the problem seems to have been resolved, although I'm not sure what did it.

 

• I may have changed my connection address to url.craftersland.net, which skips the hub world, although I'm not certain what address I was using before
• I changed launchers from the deprecated standalone launcher dating back to before the Twitch launcher which I had been using out of stubbornness to the new launcher which works through Overwolf.
