Unable to FTP into Azure web app - azure

Question

This problem first came about when I learned that a client of ours was running into permission errors on their site.

So I tried to connect to the server with
ftp://waws-prod-bay-###.ftp.azurewebsites.windows.net
to troubleshoot the issue. Unfortunately, it errored out with the following message.
Can't connect to 'waws-prod-bay-###.ftp.azurewebsites.net' on port 21. Check the server name and proxy settings. If the settings are correct, the server may be temporarily unavailable.
So I tried creating a second ftp user, since the current one wasn't shown in the FTP/DEPLOYMENT USER field underneath the app's properties. This failed too.
Then I tried downloading the publish settings and used the credentials in there. No luck.
Lastly, I tried creating a new a new app to see whether it was a problem for all apps on the account or just the one. While it took much longer than usual to initialize, I was able to ftp into it once it was done.
Any ideas on what the problem is? I had found this, which lead to
this which says the problem (or a similar one at least) was resolved about 8 months ago.
Thanks for the help.
Edit:
I am able to ftp now, but I'm not going to flag this as resolved, since I don't know what fixed it. If anyone encounters this issue, please try juvchan's suggestion in the comments.

Answer 1

I would recommend trying the following to gain access
The simplest thing to try would be to restart the app in the portal. I've seen this same issue and restarting the app fixes it.
If that does not work, try actually resetting the deployment credentials rather than adding a new user.
To reset your deployment credentials go to the web app blade, click on All Settings -> Deployment Credentials. It will then let you reset the username AND password. Again; I have seen this as an issue too.
