Unable to install mods

Having issues with ark-server installing mods.

I see the below in my logs:

Steam Console Client (c) Valve Corporation - version 1676336512

Repeating for each mod.

If I try installing via arkmanager in the container, I get the following:

steam@423bac71de71:/app$ arkmanager installmods
Running command 'installmods' for instance 'main'
Downloading mod 1333158793 ... User ******** login failed - please login to steamcmd manually

Repeating for each mod.

Steamcmd on the server:

I'm hoping I just missed something with the Steamcmd portion of the instructions; let me know what else you might need from me.
