Hacking error code: 2144-0001

[movietime]

I am newbie and trying to understand the Switch I recently bought has SX OS 2.0.1 installed on OFW 4.1.0
I have read in the forums about this infamous error. I keep getting it atleast once a day and I'm not even getting into the album 47 times.
e.g., ARMS was working flawlessly single player. When changed to multiplayer I got this error. Then I inject the Switch and ARMS started working ok. Today I copied new game and shorten the .XCI game names and removed extra stuff from the name. I tried ARMS today and I got the same error as soon as it ran.
I don't think it's SD card related because nothing has changed and the same game works and give out error other times.
Thanks for your advice.

Did you use your switch in Dock Mode? if yes update to SX OS 2.2 Beta that have fixed many bugs that give the 2144-0001 Errors

When changed to multiplayer I got this error.

SX OS has "stealth mode" that blocks comunication with nintendo's servers. I dont know if its the direct cause of the error, but you cant go multiplayer while on CFW

Even multiplayer offline ?

Even multiplayer offline ?

If you mean local play as in LAN play then no. "Stealth Mode" only blocks online MP

Even multiplayer offline ?

Yes, I haven't configure the Internet connection at all. Everything is offline and local only
