Hi, Gustavo.

Thanks for reaching out, it seems to be a problem with TLS version mismatch during handshake. You can double check TLS version of Azure Function app, (TlS 1,1.1,1.2). Just change it to 1.1 and then back to latest. This might solve the problem. I`m using some apps with lower version for compatibility with legacy apps.

I`m not sure how to check a SSL type on a logic app and sync it with an Azure Functions app. But its something to investigate.
