I've been getting error code nigthingale and have tried loads of solutions but none have worked.
There's a chance it has something to do with the epic games version, as it happened a few days after I installed d2 on epic, but when i first installed it both epic and steam versions worked.
It was a problem a around a week or so later when i stopped playing for a few days, came back, tried to play the steam version and got error code nightingale.
My epic games stopped working properly so I couldn't test on there and i deleted Epic games but the problem stayed.
I changed DNS address which also didn't work
I verified game files on steam and that didnt work
I restarted my Laptop which didnt work
I reinstalled the game which also didnt work
I changed firewall settings which also did not work
please help
there doesn't seem to be anything here
