Not being able to join anyone's worlds/servers, nor can anyone join mine, switch keeps giving communication error whilst trying to join.

I bought DST a couple of days ago. The first 2 days I could play without any errors, I played together with my partner on their server on my wifi network. The next day I wanted to join their server again but switch gave me a connection error with code:2306-0532. I tried joining other people's servers but it gives the same error. People can't join my server either. I have been trying to fix this issue for 2 days now but I'm running out of options. I followed both Klei's trouble shooting steps and Nintendo's, but the error still occurs. I have reset my internet router and I reinstalled the game as well. I tried changing the DSN settings, but nothing seems to work. Every other device in my house works perfectly fine on my internet. I tested other online games on my switch and they are still working fine, DST seems to be the only game having issues with connecting. My internet has 60 Mbps Download and 40 Mbps Upload so it should be okay. I have played the game for 2 days online and it had no issues with my internet. Without anything having changed in those 12 hours, it suddenly just stopped begin able to play online, which is a shame because I just bought this game and now I can't play.  I don't know if my account specifically got bugged or the game itself. Please let me know if there's any other options I can try to fix this!
