About MsaServer issue

Hi , I want to build MSA service through MsaServer inside ColabFold, and I want to let other users use localcolabfold to search MSA in the MSA service I built. but I'm having 3 problems.

1, I don't know how to make sure the MSA service is built successfully? Is there any easy way to test it?

2, About the ColabFold/MsaServer/config.json content, it is as follows:

{
    "app": "colabfold",
    "verbose": true,
    "server" : {
        // you might want to change the port
       	"address"    : "127.0.0.0:80",
        "dbmanagment": false,
        "cors"       : true
    },

My server IP is 157.148.21.131, so do I need to change 127.0.0.0 to 157.148.21.131? Does the port always need to be set to 80，and is it possible to change it to another port?

3、To provide external service, do I need to change "ExecStart=/path-to-mmseqs-server-home/msa-server -local -config /path-to-mmseqs-server-home/config.json" in ColabFold/MsaServer/systemd-example-mmseqs-server.service to "ExecStart=/path-to-mmseqs-server-home/msa-server -server -config /path-to-mmseqs-server-home/config.json”

Start with ColabFold/MsaServer/config.json and ColabFold/MsaServer/systemd-example-mmseqs-server.service, then trace how the MsaServer is started for local and external use. Define a simple service verification procedure and document the address, port, and service-mode settings needed for localcolabfold clients.
