Using a XXXXX servicebus.windows.net, the connection from within the company is being allowed via the firewall port 443, nothing special, but we keep getting intermittent connection issues. The connection times out causing the application to fail preventing the software from being setup properly. There's a service "Haufe FabricHostService" that keeps crashing as well, "Host for Lexware ServiceFabric Servers" . Please let me know what other information is needed to help troubleshoot, thank you.

    Hi there,

    The major cause for intermittent connection issues is hitting a limit while making new outbound connections. The limits you can hit include:

    TCP Connections: There is a limit on the number of outbound connections that can be made. The limit on outbound connections is associated with the size of the worker used.
    SNAT ports: Outbound connections in Azure describes SNAT port restrictions and how they affect outbound connections.

    You can follow the steps in the below article for detailed description of the steps that you need to follow .
