无法通过FTP进入Azure Web应用

Question

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

[IOException: The media is write protected.]

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.
