Frequent Error 86420

      Frequent Error 86420

      Several times recently, I've tried playing Intermezzos with my friend and our sessions are filled with random disconnects during matches / between rooms. Often times this is followed by me getting error 86420 which lasts for anywhere between 10-30 minutes before we can play again for another short period. Both of us can play in WWs, CTWWs, and other friend rooms fine other times, but when we try to connect together we have issues. I even tried using my phone's mobile hotspot to see if it was an issue with my router but the issue persisted. My friend code is 2882-3264-1256 and his is 0693-2070-4087 if it helps. Is there any other things we can do to try to fix our issues? In the three and a half hours we played on Friday we had to have had at least 8 different rooms, with some lasting for several GPs and others barely lasting one race.
