<t>I had the same problem with my site and it turned out the issue is with the site url:<br/>
the automatically generated remote url was: https://user@site.scm.azurewebsites.net/site.git<br/>
<br/>
On the other hand the portal showed: https://user@site.scm.azurewebsites.net:443/site.git<br/>
<br/>
After updating the remote url in git with the following command:<br/>
<br/>
git remote set-url azure<br/>
https://@.scm.azurewebsites.net/.git<br/>
https://@.scm.azurewebsites.net:443/.git<br/>
<br/>
```<br/>
<br/>
things started working as expected.<br/>
<br/>
The morale of the story: check the deployment url as well as the password.</t>
