I'm currently using visual studio 2017 and trying to attach the debugger to my web app. I've deployed my app and i've attached the debugger through VS. I've also ensure on the azure portal that remote debugger is turned on. I've also went to https://xxxxxxxx.scm.azurewebsites.net/ and checked the processes and w3wp is available. From Unable to start debugging in VS2015 for Azure web app and Remote Debugging - Web App Azure it indicated to me it could be a port being blocked. so i went ahead and set my firewall outbound to allow the connections from UDP 3702 TCP 4020 TCP 4021 and ports 4022 and the problem still persist. I'm unable to connect to my connection target.
I've tried xxxxxxxxx.azurewebsites.net:4022 and xxxxxxxxx.azurewebsites.net
I'm all out of ideas and suggestions from the web. If anyone else has tips, that'll be great.
unable to connect to my connection target.
Please refer to this article to configure the firewall to enable remote debugging for VS 2017.
Remote debugging works for me using VS 2017 with following steps:
Turn on Remote debugging and choose VS 2017
Find and attach to process
Please try to enter {your_web_app_name}.azurewebsites.net:4022 and click Refresh button to check if you can see available processes.
Besides, you can right-click your web app, and then click Attach Debugger to remote debug the web app in Server Explorer.

I'm using Visual Studio 2019. I can attach the debugger to services running in my own subscription.
When I try to attach to services running in another sub from cloud explorer, I get various errors and the attachment never succeeds. The most common is:
Unable to find a process called w3wp with arguments {app service name}. The process may still be starting, please try again.
When trying to attach under the Debug -> Attach to Process dialog, I get the following error:
Unable to connect to {path}. The connection with remote endpoint was
terminated.
I have owner role on the subscription, on the app service and on the app service plan.
Please validate if you have enable debugging from azure platform side. Screen shot od the same from portal looks like:
Also please confirm if you have deploy application from VS.
Visual Studio remote debugging on azure app services used 4020, 4022, 4024 ports for debugging.

I want to use Remote Debugger in Visual Studio 2015 to attach to my site. When I try "Attach Debugger" the azure return:
The following error occurred while launching remote debugging: Unable to connect to the Microsoft Visual Studio Remote Debugger name 'XXXX'. Windows authentication was unable to establish a secure connection to the remote computer.
In azure portal I set remote debugging and select VS 2015.
These errors might be related to Local Policies > Security Options > Network Security: LAN manager authentication level. It needs to be set to “Send NTLMV2 response only”. Once this is set then the PC was able to open RemoteApp applications without problems.
To set local policies go to command prompt and type secpol.msc or Administrative Tools > Local Security Policy
Maybe your application is not enabled to use remote debugger.
To enable remote debugger in app service:
Go to Azure management portal
Select your app
Go to settings
Go to Debugging
Enable Remote Debugging
Select your visual studio debugger versión
As much as it pains me to provide this as a solution, have you tried closing and re-opening Visual Studio? (In particular if you were able to connect at one point and it stopped working.) This has solved this issue for me on multiple occasions.
Changing my network connection appeared to solve this for me. To do this, I:
Open Networking and Sharing Center
Change adapter settings
Disable the currently-active network adapter (ethernet in my case)
Enable another network adapter (WiFi in my case)
After that, Visual Studio debugged the app service.
I am trying to debug a webservice remote on Microsoft Azure. The service is running in a web role.
I have configured remote debugging in the publish settings an can attach the debugger to the web role. Also, when I have selected the correct process, the debug symbols are loaded correctly and breakpoint's tool tips say that the breakpoint is hosted in "WallSHost.exe" which is the remote process.
What I would like to do, is to run a local client software which I am developing and step into the server code from there. When I step into the according service client call (F11), I get the above error message, saying (for the sake of Google in plain text here):
Unable to automatically step into server. Connecting to the server
machine 'xyz.cloudapp.net' failed. The Microsoft Visual Studio Remote
Debugging Monitor (MSVSMON.EXE) does not appear to be running on the
remote computer. This may be because a firewall is preventing
communication to the remote computer.
I have tried to disable the firewall on my (the client) machine with no effect. Has anybody seen that before or can tell me how fix this problem?
A quick checklist
deployed cloud service is a debug build
a debug build is selected from Build Configuration list (in publish wizard)
'Enable Remote Debugger For All Roles' is checked
no changes to code since deployment
Hello i have a problem with remote debugging in Visual Studio (v12)
I Created windows azure account i published application to the cloud.
Then i connected to this account through remote desktop. Address of remote computer is f.e Iron.app.net
Then i downloaded there and run remote debugger. I started msvsmon.exe and it created server named:
RD0015555E2:555
And now i would like to remote debugging in my host.
i know i must attach to process. And i do it.
From Visual Studio: Debug->attach to process->Qualifier:RD0015555E2 and it cannot resolve host name.
i also tried Iron.app.net but then it shows error that it seems that msvsmon is not installed.
I dont know what should i type into Qualifier (as remote machine)?
Remote debugging is tricky to configure Windows Azure Cloud Services. Other options that you have are:
Intellitrace (in case you've got Visual Studio Ultimate)
Intensive (verbose) pro-active code instrumentation (logging) from the beginning.
Profiling Cloud Service
Chose either, and watch your logs/traces.
Or deep dive into Remote Debugging Cloud Services. I would, however use Remote Debugging as a final option, when everything else does not work and does not help me. Typically most of the issues that would pop in the cloud will also pop in when debugging locally. And if role is just recycling, you will not be able to attach debugger at all.
I have Windows Azure SDK 1.6 installed along with Azure tools. I have one web role (with two endpoints, port 80 for http and port 443 for https) and only have one instance of the web role running (for testing purposes).
When I ran it from Visual Studio for debugging last week, it ran the emulator, attached it to IIS with a binding of 127.0.0.1:80 and everything was peachy.
But as of yesterday, as soon as I started it was trying to bind it to 127.255.0.1:82 and it stopped working with this error (from Visual Studio):
There was an error attaching the debugger to the iis worker process
for URL 'http://127.255.0.0:82'
Now if I manually go to IIS and change the bindings back, I can access the site through a browser but obviously I can't debug it via VS.
Why is Visual Studio doing this? What made it change from last week (I've only made code changes and I have commented them out)?
Edit: I know about this blog, but my issue seems to be different because for one reason I don't have errors in the event logs. And like I mentioned as soon as I change the bindings manually in IIS, I can access the site properly so the app pool is configured correctly.
Edit2: I have the following set:
<compilation debug="true" targetFramework="4.0" />
And my cloud project is set to startup project as well.

I don't believe you ever debugged a Azure Emulator deployed project on 127.0.0.1:80 binding with IIS. There is a chance that what you've debugged is just the Web Application project and not the Azure Deployed one. Let me explain why:
Windows Azure Emulator uses internal emulated Load Balancer (LB).
This emulated LB binds to 127.0.0.1 port 80 (if port 80 is already
taken it uses port 81)
Windows Azure Tools are dynamically creating a virtual IP address
for every instance of a webrole you have. These dynamic IP Addresses
are 127.255.0.X, where X is the logical number of the instance (0,
1, 2, etc...).
Windows Azure tools creates a website in the local IIS, with binding
of 127.255.0.X and port 82
Step 3 is repeated for every instance you have defined.
When start debugging, your browser usually opens http: //127.0.0.1:81/ which is the address of the LB. But the request from this address is forwarded to the IIS and its binding to 127.255.0.X:82. You could not have debugged a Windows Azure Emulator deployed project by manually attaching debugger to 127.0.0.1:80, because, if everything was fine there is no w3wp process listening on that address:port, but Azure emulated LB.
When you only have the WebRole (no additional sites defined), Windows Azure Tools does know that it shall attach the debugger to 127.255.0.X:82 where a w3wp process is listening.
This is the clean working configuration of Azure Emulator & SDK & Tools v.1.6 (I think also 1.5 and even back to 1.3 where the Full IIS mode was introduced for first time)
Now if I manually go to IIS and change the bindings back, I can access
the site through a browser but obviously I can't debug it via VS.
Yes, you will be able to access the site, but in that way you are skipping the emulated LB, which is not the point when developing Windows Azure Applications.
If you are heving issues of that kind, I suggest that you clean your solution, restart the computer, and if the problem persist uninstall the SDK & Tools and perform clean full install of SDK & Authoring tols for Windows Azure v.1.6 using the Web Platform Installer.
