THE REAL ISSUE is the connection failure carries over to other applications that rely on Steam like project zomboid:

admin@576596f95bac:~/app$

i can't use box86 for running project zomboid because the libraries are only for 64 bits, the server works if i run without steam (but i need steam unfurtunally)

box64 and box32 tested in this docker file: steamcmd-docker-arm64
