I have read somewhere about setting the TLS to 1.2 in the applicationstart might solve the problem, its currently set to 1.2 in azure.

I am aware that you have retired this package but any help on this would be much appreciated.

Many thanks

@khraibani ah yes that does look like it might be the TLS version - there is a package - https://our.umbraco.com/packages/developer-tools/codesharetls12umbraco/ or you can incorporate the setting into your own codebase from - https://github.com/prjseal/CodeShare.TLS1.2.Umbraco/blob/master/CodeShare.TLS1.2.Umbraco/EventHandlers/RegisterEvents.cs#L8

@Jeavon for the swift reply! I will give it a try.
Happy Easter!
