Server Crashes and can't login with no errors when you do anything in game :(

If the databases are loaded properly already as you checked in SMSS, I think you need to make sure that your services can connect to your database.
check IPs, Ports, Usernames, Passwords in the /etc/cabal/*.ini files.
Is your database running on the same vm as your services? (to eliminate the network issues)

I've seen this in your logs,
[Wed Apr 15 2020 16:42:49.617325 4097772352]: [##ERROR##] DB ERROR(MSG) : [FreeTDS][SQL Server]Read from SQL server failed.[Wed Apr 15 2020 16:42:49.617377 4097772352]: [##ERROR##] DB ERROR(CODE) : 20004[Wed Apr 15 2020 16:42:49.617388 4097772352]: [##ERROR##] DB ERROR(VAR_INFO) : [Wed Apr 15 2020 16:42:49.617397 4097772352]: [##ERROR##] DB ERROR(SQLSTATE) : 08S01

DB ERROR(SQLSTATE) : 08S01 -> Google says that this is a connection failure.

I've set all the right IPs, Ports, Username and Password in all of my .ini files. What do you mean is my database running on the same VM? Yes I think I'm only using one VM the IP of the VM and the Database is the same so yeah? Do I need to separate them? I don't understand why when I tried it offline it doesn't have any errors. Do you have email that we can exchange messages?

Wed Apr 15 2020 15:52 ===== *&&&&* bad Paket key >> Invalid CharIdx no pUserCtx to inject in ChatNode
EventMgr get Wrong Paket Key, GlobalDBAgent is Connected with DB but the FreeTds say Read From SQL is ERROR
[##ERROR##] DB ERROR(MSG) : [FreeTDS][SQL Server]Read from SQL server failed.

I fixed it. Azure VM can't handle a using 1 VM for server and database. I fixed the error by installing the dabatase and the server with two seperate VMs. In contabo vps I have no problem using only 1 VPS with the server and database, but 3gb ram with 2cpu can't handle 20 channels. just 5-8 channels i guess.
