Not able to connect Azure - Web App using FTP

Chandrakant Pawle 101

Hello

Not able to connect Azure - Web App using FTP - Winscp or FileZilla. Have enabled Web App->Configuration -> General Settings -> FTP Basic publishing credentials.

Set Configuration -> FTP state = FTPS only

Pls tell me if some more configuration required? Thanks

Regards

Hi Chandrakant,

If using FTPS Only, you must enforce TLS 1.2 or higher by navigating to the TLS/SSL settings page of your web app. TLS 1.0 and 1.1 aren't supported with FTPS Only.

Please check for more details -->https://learn.microsoft.com/en-us/azure/app-service/deploy-ftp?tabs=portal

Can you please check this once and update ,

Please accept answer if it helps , Thanks!

I also face the same issue while connecting Azure - Web App using FTP. This was working fine earlier (a month ago) for me. I tried all the settings described above by @VenkateshDodda-MSFT but to no avail so far. The only thing I performed recently on the existing web app was the migration of the App service environment from v2 to v3 (which of course changed the IP address of the ASE v3 during migration).

@Chandrakant Pawle Thank you for posting your question in Microsoft Q&A, apologize for any inconvenience caused on this.

Mitigation or Workaround steps:

If you are using application scope credentials to FTP to app service, then make sure that both SCM Basic Auth Credentials and FTP Basic Auth Credentials are enabled and also FTP state to FTPS only.
If you are facing any issue while following the step1, then I would suggest you try connecting to FTP through user scope credentials.

Update:

Our engineering team has investigated the issue and identified a bug in connecting to FTP service using application scope credentials.

They are working on fix and fix will be rolled out in next release. If any other customers are facing the issue I would suggest you follow the above steps to connect to app service using FTP.

Let me know if you are facing any issue or if you have any further questions on this.

I am facing the similar issue as FTP was not connecting using Application scope credentials. Following the work around provided, i have created user scope credentials. They worked fine. But the issue is i have 2 web apps in the azure tenant (Non-Prod and Prod). The files are getting updated in Non-Prod website even tough the changes are made using Prod credentials following the format "appname/username"

Could you please help.
