I can also confirm this bug, it has been present since Proton became available and I have been following the progress on #162.
I have done the linking of the system libgnutls to the Proton folders, however, MyLeague still is unable to contact the 2k servers.
Manjaro Linux, Latest Steam version, Proton 3.16-7 beta. I do own the game and am happy to test anything or post any logs, though I am unsure where they are located.
Here is the log from attempting to launch the game and connect after enabling logging in the launch options for NBA2k19.
Also, here is the terminal output from an attempt at using steam-runtime with no change. (Apologies, was not able to attach two files in one post.)
I can confirm that this bug has been fixed as of Proton 4.2.
Thanks, devs!

I confirm:
I do not have proton log and It was trial and time expired. I decided not to buy the game due to performance issues related to my computer and the fact that online mode is not available
Reproduction

Same issue for nba 2k18
