Hello Bagus Sutikno,
1.Please check the repository URL, it should match the one configured in mendix project setting.
2.Try selecting yes to keep me signed in.
3.go to your C:\Users\123445\AppData\Local\Mendix and clear the cache credentials.
You need to enter your PAT(Personal access token) as password.
Go to GitHub → Settings → Developer settings → Personal access tokens
Click “Fine-grained tokens” or “Classic token” (classic is easier for Mendix currently).
Click “Generate new token”
Set:
Expiration (e.g., 90 days)
Scopes: Check at least repo
(full control of private repositories)
Click Generate token
From what I've heard, the username you enter there can be basically anything, but the password has to be a Personal Access Token that you created on your profile. Is that the password you're curerntly trying?
I also get this issue from time to time, when I didn't process the web login when loading the project.
Try to close Studio Pro, open it again and before loading the project click the link for the web sign in. Then login to mendix in the browser window that should have been opened. When the login is successful, you don't have to login when doing a commit anymore.
