Web Deploy to Azure fails “Could not create SSL/TL

I always deployed from my local machine to Azure (Classic cloud service) but from yesterday I get this error:

Could not complete the request to remote agent URL 'https://[MYNAME].cloudapp.net:8172/msdeploy.axd?site=Default Web Site'.The request was aborted: Could not create SSL/TLS secure channel

The port is open. The web deploy is installed. As I see nothing has changed. I tried to install a new version of Web Deploy (3.6) but it didn't help.

What else can be checked?

Thank you.

i faced the same problem: old 2008 r2 Server never changed anything

cause (speculation): since visual studio 15.9 they disabled SSL 2.0, TLS 1.0, etc. so it cant communicate propper with the old webdeploy

solution: enable TLS 1.2 on old webserver (and disable the old ones)

i found this link: https://developercommunity.visualstudio.com/content/problem/384634/webdeploy-netcore-api-to-iis-vs159.html

which linked to this blog: https://tecadmin.net/enable-tls-on-windows-server-and-iis/

Step 1 – Backup Registry Settings We strongly recommend taking a backup of the registry before making any changes. Use below link to find steps to how to export registry values.

Step 2 – Enable TLS 1.2 on Windows You have two options to enable TLS version on your system.

Option 1 – Merge Resistry File Download the Enable-TLS12-Windows.reg and Enable-TLS12-TLS11-Windows.reg files on your Windows system. Now right click on file and click Merge.

Step 3: restart.

PS: First i tried the "Client" way, which doesn't work for me. But maybe it helps some one:
