tacit rock
I've installed Nimbus from Universal Updater and changed game servers to Pretendo. I couldn't create PNID on the 3ds itself because of some error, so I created it on the website and linked it on my console. It worked fine, and I was able to browse Miiverse and change PNID related stuff in settings. After that I went a few days without connecting my 3ds to internet. And now whenever I'm trying to launch Miiverse or open NNID settings in the system settings app I'm getting a screen that just says "Checking Nintendo Network ID Credentials" infinitely. I've already tried to reinstall Nimbus and change servers from Pretendo to Nintendo and back. Tried rebooting and leaving my 3ds on that checking credentials screen for a good 30 minutes, but no luck
