this code works fine when running on the same VM as LakeFS, but instead it seems hanging on

o.reader(mode='r')

when running from my machine connected to the VPN where LakeFS is running

clt = Client(username="..", password="..", host="<http://192.168.11.104:8000>")

repo_id = "demo-flame"
branch_id = "s01"

print("    E ", repo_id, branch_id)
repo = lakefs.Repository(repository_id=repo_id, client=clt)
branch = repo.branch('main')

o= branch.object("demo_data_project/SCHEMA.json")
print("    O ", o._client)

r= o.reader(mode='r')
print("    R ", r)

schema = r.read(20)
print("    S ", schema)

any idea what it could be? I managed to reproduce the same error on another vpn-connected machine..
