Sudden timeouts of Azure Function

Symptom

Suddenly, you get exceptions like this:

The reason is that Tayfun whitelisted the IP addresses. But microsoft changes them from time to time.

See tickets #7614 and #1224.

Resolution

Ask Tayfun to adjust the whitelist.

Mail

Dear Tayfun
Microsoft has updated the IP addresses again. As a result, the Azure Function cannot connect with the Platform.
Could you please update the IP Whitelist?
You'll find the latest list at https://www.microsoft.com/en-us/download/details.aspx?id=56519
We are interested in the IP addresses / subnets listed in this section:

"name": "AzureCloud.switzerlandn",
 "id": "AzureCloud.switzerlandn",
 "properties": {
     "region": "switzerlandn",
     "regionId": 66,
     "platform": "Azure",
     }

Thank you so much in advance!
