Error message when publishing version 2.0

I hope everyone is okay! I'm trying to publish version 2.0 of an app and Volt returns this error message:

ERROR mf appinfo publish error: ERROR: HTTP GET on http://172.16.31.150:8080/authService/100000002/appconfig?compositeSvcDoc=true failed for [Fetch service document of app] with status 401. Details - {"details":{"message":"Invalid App Credentials found in Request","errcode":0,"errmsg":"Invalid App Credentials found in Request"},"httpstatus":"Unauthorized","requestid":"14019f4f-5baa-4c7c-9071-9ac9e1966299","domain":"AUTH","code":-9,"mfcode":"Auth-9","message":"Invalid App Credentials"}

Can someone help me?

For which platform, are you building the application? And are you building it locally or publishing it to the enterprise app store?

P.S: I don't know anything about the problem, but I was curious to know which action triggered this error?

Hello,

It's hard to say definitively what could be causing this error with the information provided. Are you publishing from Iris? If so, can you try to unlink the app in Iris, refresh the app (from the Project menu) and link it again? After this, test publishing it again.
