Online play with pretendo not working on the Linux flatpak

[randomoOCoder]

Current Behavior

The emulator does not connect to the pretendo servers for online play on Linux. This issue is mentioned on cemu.cfw.guide. However, unlike what is mentioned on that site, running cemu through wine still has the same problem. The issue only affects the windows build run through wine and does not happen natively on windows.

Expected Behavior

The emulator connects to pretendo allowing you to play online, at least on the windows version through wine and preferably on the native linux build.

Steps to Reproduce

Download any version of cemu (windows or linux) and run it on linux, setup online functionalities, and try to play an online game.

I also have this issue but for me its only the native linux version from flathub, i have cemu running on proton for only splatoon. Have you tired adding the cemu exe to steam and running it there?

Please provide errors/logs from latest Linux build. See #1189 for an example of a good report.

That 3rd-party guide has not seen any real updates for 2 years.

Are you sure your files are in the right locations?
You also didn't specify which version(s) you tried running.
When you open Cemu, and click File -> Open Cemu folder, that directory is the one in which your otp.bin and seeprom.bin need to be stored.

Also, last I tested (2.0-91 iirc), using Pretendo to play online works on the native Linux build. I was able to play Splatoon online for multiple hours.

OK, I retried dumping the online files and it worked on both the appimage and the windows version through proton on the latest release (2.1) (I must have made an error when testing it last time). However, the issue still persists on the flatpak (on version 2.1 as well). I even tried deleting the mlc01 folder as well as the otp.bin and seeprom.bin files and then recreating them but it didn't work (even though it worked for the appimage). I made sure to put the files in the correct place (~/.var/app/info.cemu.Cemu/data/Cemu for the .bin files) and then merged the mlc01 folders (at ~/.var/app/info.cemu.Cemu/data/Cemu/mlc01).

Edit: After testing the flatpak on mario maker I get the error code 106-0526 followed by an infinite loading screen (It works fine on the appimage).
