(10.14.3: Mojave AppStore and other services accepts credentials but nothing happens)

[ChristerJohn]

The only working thing is my iTunes, else does nothing when accepting my 'correct' credentials
All threads posted on this forum have been tested (en0, NullEthernet, etc...)

Any new fixes for this? It doesn't say any errors, just accepts email and password then still not logged in.
Thanks in advance

Hi, I have the same problem too.

-The Ethernet connection is en0 Built in ...
-Itunes, icloud, etc. work properly ...
-I tried different configurations of SMBIOS ...

On appstore I see my account logged in, but I can't download apps and if I try to view account information, I get an error connecting to the servers.
I don't know what to try to solve.
