Then i install parse-server from source code and run npm start -- --appId UE7SmtidKby874Q8l2Vaq0FWFu5k6lcUiPisAEnV --masterKey BOyE27IdB8GKT0Jw5nTUmqoSWDfBAdc6PCOwCwqM --databaseURI postgres://postgres:123456@192.168.101.104:5432/postgres --serverURL http://192.168.101.5:1337/parse on windows, parse-server startup without any error.
But when i restart parse-dashboard and login,the parse-server from source show one Error:

You might need to set masterKeyIps depending on your Parse Server version

@dblythy Thanks for your answer.

Maybe，i have solved this error by run npm start in the dir generated after run bootstrap.sh.

PS C:\...\parse-server\parse-server-from-source> npm start

> start
> parse-server config.json
> .....

This error occurred, when i run npm in parse-server

PS C:\...\parse-server> npm start -- --appId UE7SmtidKby874Q8l2Vaq0FWFu5k6lcUiPisAEnV --masterKey BOyE27IdB8GKT0Jw5nTUmqoSWDfBAdc6PCOwCwqM --databaseURI postgres://postgres:123456@192.168.101.104:5432/postgres --serverURL http://192.168.101.5:1337/parse

You might need to set masterKeyIps depending on your Parse Server version

parse-community/parse-server#8316

Thanks, i solved it by adding the startup param: --masterKeyIps 192.168.101.5

[mtrezza]

Can we improve anything in the error message here to make this clearer for the developer? I think this is the 3rd issue I came across recently where masterKeyIps was not set properly.

[dblythy]

Could we add a log to the server side such as attempted to connect with a valid masterKey but from an invalid IP: ip. Add ip to config option masterKeyIps to allow this request

[mtrezza]

Yes, I think it's good to keep it deliberately ambiguous and only log server side.

Request using master key rejected as the request IP address '1.2.3.4' is not set in Parse Server option 'masterKeyIps'.

@zhangwb1996 just a note that your post above includes sensitive information such as master key; if you decide to publish your app it would be good to change these keys.
