Azure Function Outgoing SSL Exceptions

Hi,

Having a problem that seems to have occurred without me making any changes.

My Azure Functions are having issues connecting via SSL to external APIs (My functions talk to an Azure Table Storage account via HTTPS)

The logs I'm seeing are similar in both functions:

Microsoft.Azure.Cosmos.Table.StorageException : The SSL connection could not be established, see inner exception. ---> System.Net.Http.HttpRequestException : The SSL connection could not be established, see inner exception. ---> System.Security.Cryptography.CryptographicException : Error occurred during a cryptographic operation. at Interop.Crypto.X509StoreSetVerifyTime(SafeX509StoreHandle ctx,DateTime verifyTime) at Internal.Cryptography.Pal.OpenSslX509ChainProcessor.InitiateChain(SafeX509Handle leafHandle,X509Certificate2Collection customTrustStore,X509ChainTrustMode trustMode,DateTime verificationTime,TimeSpan remainingDownloadTime)

Not a clue what's causing this other than maybe something to do with the clocks changing (British Summer Time) on Linux?

Is someone able to help please?

Thanks
Ben
