The advantage of doing so is that I can immediately enable a passive FTP server, because “passive” essentially means that it can choose ports dynamically. With this configuration I can communicate directly with my VM instance using the public IP address. However the easier solution is to enable an instance-level public IP address for that VM instance. If I want to make a VM instance available across a range of ports, I have to specify the ports by adding them as endpoints in my Azure management portal. So I tried options (2) and (3).Īfter trying out all kinds of configuration and creating incoming rules and Azure endpoints to allow traffic, it finally dawned upon me. It’s white actually but you get what I mean. I wasn’t even going to try to fix what’s in my “thing” because this “thing” is pretty much a blackbox, if you will. Only (1) worked, but my “thing” could not upload the event data into an Azure website FTP server. A Windows Server 2012 R2 Datacenter running FTP Server So why is this an error? Before jumping into a conclusion that this is a bug in the FTP connector, I tried 3 different options for having a FTP server in Azure:ģ. This is super weird because “227 Entering Passive Mode” is hardly an error, it’s a valid FTP status message for passive mode. “message”: “Unable to connect to the Server. When I clicked on the “Output Links” in my trigger history, this highly elusive message was shown: More about this IoT scenario I am working on in a later post.įor the past few days, I’d been stuck looking at this one error. But in this particular IoT scenario, it is hardly a workaround, it’s a necessity because the “thing” could only upload my payload in an FTP server or send an email with the payload as attachment. Due to the trigger function not yet implemented in the Azure BLOB connector, I found a workaround which was to use the FTP Connector, then use the Blob Connector as an action. I particularly like the FTP Connector and the Azure BLOB connector. It reminds me of the good old days of workflows in WF except that this meant for simple workflow logic, but it does the trick.
