Earlier before I find out this incident, I was trying out the Multiplayer and testing out features in that mode and I changed the network address to "multi.notetternaonline.com" at that time.
In the present today, around 5-6PM I was regularly playing a couple of ranked files without thinking of changing the network address because I thought it would work perfectly fine, but I was wrong. After I check my profile that my scores weren't uploading to the website, then I instantly changed the network address back to "multi.etternaonline.com" and played the recent file that I haven't play before to see if it'd upload the score or not, and the result is none.
Right now, I'm not sure on how to fix this issue anymore. I've tried log-out and log-in, refresh the game, checking on my internet connection, and took a look inside the "Etterna.xml" files. A help would be appreciated! 🙏
