I have an ARM embedded processor that talks to a .net WCF SOA (SOAP) web service application. The ARM device is remotely located and web service is hosted in a WS2k8 cloud server. I am having some protocol issues with the ARM code and would like to run Fiddler on my WS2k8 machine to observer the SOAP exchange between the embedded device and the web service application. I installed Fiddler Web Debugger V4.4.8 on the server but it does not capture any http requests. I know the ARM device is talking to my web services as it responds to several good SOAP exchanges. Anyone know how to set up Fiddler to work in the configuration I have explained?

They way I fixed it was to set in the client application to use a proxy ( :8888) so now the calls are redirected to fiddler and fiddler call the services, so I can see the traffic. Hope it helps someone

I have been debugging my software by connecting an iphone which is on the same network. Then I use fiddler on my desktop/server and set it to Allow Remote Connection (instructions here). I had this configuration working under Windows Server 2012, since I've upgraded my server to Server 2016 I am no longer able to get the phone to connect to the proxy server at xx.xx.xx.xx:8888. I checked "Allowed Apps" in the Windows Firewall but I don't see anything that looks relevant in there.

I figured it out. I changed the firewall settings in Windows firewall to ask me if an app was going to be blocked. After restarting fiddler I was prompted and I said yes, allow this app to go through the firewall and then it started working.

To download the Fiddler add-on, go to the Internet Explorer add-ons page. For more information about how to troubleshoot by using Fiddler and related tools, see the How to use fiddler and HTTP replay to have an offline copy of your site blog post and the Troubleshooting Authentication with Fiddler blog post.

I've got a bit of a tricky application I need to monitor. Its a Java .jnlp file. Using Process Monitor, I've been able to identify it (its instance of javaw) going out to the other servers in my network; however, running Fiddler, it shows no activity what-so-ever. I do know the traffic is HTTPS encrypted, and it appears to be connecting on ports which my servers are running web servers (tomcat). With Process Monitor I can see the length and direction (send/receive) that the data is going, but it doesn't even show me the encrypted contents.

The server software that this jnlp is communicating with, is installed as a "package" and I have not been able to find any SSL certificate files within the directory of this application. I've used Wireshark, but without the private keys, I haven't been able to decrypt the traffic.

I'd run the offending program in a VM w/ a Linux-based VM acting as its default gateway. You could then use some iptables NAT rules to redirect the connection attempts to a HTTPS-to-HTTP proxy that, in turn, forwards the request on to an HTTP-to-HTTPS reverse proxy and, ultimately, to your servers. You would be able to log the traffic when it's in an HTTP state between the proxy and reverse-proxy servers. It's not elegant (and somebody else can probably think of a cleaner method that uses fewer moving parts) but you could do the whole thing with off-the-shelf software (I'd probably use a couple instances of nginx). Presumably the offending application isn't authenticating that it's actually talking to your servers but, if it is, you could just export the SSL certs and private keys from your servers to make the deception "complete".

This certainly assumes that you have access to the private keys for the servers your application is talking to. But if that's the case, you should be able to pull this off without too much of a problem.

Ok, this interesting. My machine, which was working correctly all the time is now presenting the same issue. I installed fiddler and I can see that in fact it seems to be a certificate issue. Since this happens in my machine, I can confirm that RequestLog is empty.

HTTPS is a secure version of HTTP. When making a connection using HTTPS, either SSL or TLS will be used to encrypt the information being sent to and from the server. This encryption makes it very d...

Wait no, sorry, confused the error message. That Message you are showing happens in my working computer, whenever I try the application with fiddler working and not having the Ignore server certificate errors.

Remember to mention the IP Address of the servers involved so Atlassian Support can use that to filter through the TCP dump. Also, include the timeframe of when you performed the operation requested by support.

All you need to do is set a breakpoint to pause the processing of the session and permit alteration of the request/response. You can also compose your own HTTP requests to run through Fiddler. Fiddler lets you see the \"total page weight,\" HTTP caching and compression at a glance. Isolate performance bottlenecks with rules like \"Flag any uncompressed responses larger than 25kb.\"

Fiddler is a free web debugging proxy server tool that logs HTTP(S) traffic to quickly obtain all network communications to and from the device. Instead of requesting and analyzing verbose server logs, you can significantly reduce Windows 10 troubleshooting efforts by using the Fiddler tool.

The upper window shows what is sent from the device to the endpoint, and the lower window shows the response from the server to the device. When Fiddler is first launched, it attempts to check for updates and sends its current version. The server then replies with the latest version of Fiddler and the release notes for the latest releases. This is a simple example to show the type of information we can retrieve, but for our troubleshooting, we can use this method and tool to debug enrollment issues and push profiles, for example.

Check if the device's date and time are correct, especially when using a virtual machine. This prevents any SSL-related errors due to the date and time being out of sync with the server time. This simple step should always be completed if you encounter enrollment issues or failed check-ins.

For this step, use a static or local email address. This is not the email address that you used to log in to your environment. Normally, your user community would enter their corporate email address which would then point their device to your Workspace ONE UEM environment. If you choose not to use a WADS server then the user would be forced to enter the enrollment URL manually. This is no longer the recommended enrollment method; end-users should enroll by navigating to

The most effective method to pinpoint why Workspace ONE Baselines are not functioning properly is to understand the high-level process flow. The following diagram shows which component to focus your troubleshooting efforts: Workspace ONE Intelligent Hub, the local Baselines folder, or the Workspace ONE server components.

Windows Desktop introduces several new configuration service providers (CSP) to push out windows apps and desktop MSIs. Workspace ONE UEM supports not only MSIs (like most of our MDM competitors) but also supports MST, MSP, EXE, and ZIP through Software Distribution.

Important: As a requirement for environments using CDN servers for file distribution, enrolled devices must have open access to the internet. The CDN network has a distributed architecture around the globe, and VMware cannot guarantee that a specific file download to a device will come from any individual server. The system is designed to increase the likelihood that a device will download a file from a server in a similar geographic location.

If you have an environment where devices cannot connect to the CDN architecture (for example, due to a strict firewall configuration that allows access only to certain websites/servers), please refer to this KB article: Introducing IP Limited Content Distribution Network (CDN) capabilities in Managed Hosting SaaS Workspace ONE Environments.

Lastly, if the connection to the CDN provider fails, the content (for example, an application) is pushed from the Workspace ONE UEM Device Services server, as it would be if CDN integration was not configured.

Keeping your Windows Desktop devices up-to-date helps to protect them from security risks and viruses. Because Microsoft has moved Windows 10 and 11 updates to a continuous cycle known as Windows as a Service, Workspace ONE UEM can now manage the update life cycle. This exercise helps you to explore some of the high-level windows update troubleshooting tasks to get updates working and validate that they are set correctly.
