We are getting below error on Azure devops pipeline via Self hosted agent release when Azure web app is on Private network. No Error seen when the web app on azure is on Public.
Error: Error: Failed to deploy web package to App Service. Error: tunneling socket could not be established, statusCode=503
Made Azure web app to private and error comes. Moved to public no error seen.
Seems that the self-hosted agent cannot connect to the Azure app service. It seems to be a network issue.
The agent needs a way to connect to the App service directly. To ensure the connectivity is ok, we need to make sure the self-hosted agent is not blocked by NSG rules or App Service networking Access Restrictions. Just whitelist the agent machine in your rules.
The task using Kudu REST API to deploy the application. We need to check the following App Service networking Access Restrictions to allow deployment from a specific agent:
Make sure the REST site “xxx.scm.azurewebsites.net” have Allow All, i.e. no restriction.
Also, the option “Same restrictions as ***.azurewebsites.net” should be unchecked.
If you are using Private Endpoints for Azure Web App, you must create two records in your Azure DNS private zone or your custom DNS server. Kindly check DNS for more details.
Besides, when the proxy is set up, Web API calls and SCM hosts are bypassed by the user. The same has to be configured in the Azure pipelines agent explicitly. To bypass specific hosts, follow the steps here and restart the agent.
1.Allow access to Public removed.
2.Created Pvt endpoints within same Vnet and Subnet of Target VM
3.Created new file .proxybypass in self hosted agent folder C:\Username\Agent
4.Added below entries in .proxybypass to allow and communicate bypassing corporate proxy

According to Configuring the Artifactory Service Endpoint, an artifactory instance as service endpoint need to be configured. One of the parameter is the server URL to the artifactory. What if the server URL is a local intranet, will the URL be considered valid ? I am having error with the URL I am providing (Local intranet). The error is:
"Failed to query service connection.....Error Message:'An error
occurred while sending the request'"
What if the server URL is a local intranet, will the URL be
considered valid ?
While the server URL you used here is a local internet, which means our azure image(Hosted agent) could not get communicate with it from public internet. That's why the error message told you failed to send request to server.
So, here the best way is you need configure one self agent in that local machine.
BUT, if Hosted agent is one preferred choice in pipeline execution. I'm afraid you have to configure your artifactory instance to make it accessible from the internet, just like the URL in the blog you shared above. Because our Hosted agent actually is Azure VM which hosted in cloud.
I want to register a target using a registration script generated by Azure DevOps. My production server does not have an active internet connection, will the registration script work?
If not what Url's do I need to specify in the proxy to allow that communication?
You'll need to be able to access the URL for your azure-devops account to register an agent. You can also reference this documentation for whitelist addresses.
I can't connect from azure resource (aks node) to Azure postgres using pgcli. I also tried directly from node and got the same error message:
FATAL: Client from Azure Virtual Networks is not allowed to access the server. Please make sure your Virtual Network is correctly configured.
Firewall rules in the resource are on:
Allow access to Azure services: ON
Running the same pgcli login command on my computer and on another azure resource seems to work fine.
Adding Firewall rules to all IPs return the same error.
Curl from the problematic server (host:5432) returns a reply, so it's not an outbound issue.
What does the error mean?
A VM where the connection originates from is deployed to a virtual network subnet where Microsoft.Sql service endpoint is turned on. Per documentation:
If Microsoft.Sql is enabled in a subnet, it indicates that you only want to use VNet rules to connect. Non-VNet firewall rules of resources in that subnet will not work.
For connection to succeed there must be a VNet rule added on PostgreSQL side. At the time the question was asked VNet Service Endpoints for Azure Database for PostgreSQL just got to public preview so I assume it might not have been available for the OP.
Solution
As of November 2020, Service Endpoints for Postgres is GA and instead of disabling the service endpoint one can add a missing VNet rule to the PostgreSQL server instance and reference the service endpoint-enabled subnet. It can be done via Portal or Azure CLI
Apparently, the vm is part of a vnet that a service endpoint tag Microsoft.sql was enabled.
I found this answer. To solve the problem I disabled the service endpoint and added the public IP to the Connection Security section.
I encountered the same problem.
All I did was to switch Allow access to Azure services to ON .
We have an Azure App Service Environment, which resides in a subnet in a vnet configured with both an expressroute gateway and a VPN gateway. When trying to connect an AppService outside of the ASE to the Vnet, as described here: https://learn.microsoft.com/nb-no/azure/app-service/web-sites-integrate-with-vnet, we are not able to connect, because it says the gateway is not a VPN gateway.
I suspect the GUI only picks the first gw in the list when it tries to figure out what type of gw it is.
Because, we do have a vpn gateway too:
I have a couple of questions:
Is there a way to get the Portal to use the correct gateway when
trying to connect from the AppService to the Vnet?
If not, is there a way to do this from Powershell with the AzureRm CmdLets?
Currently, it is not possible. It is a design behavior. Integrate web app with an Azure Virtual Network does not support Vnet that has an ExperssRoute Gateway. If ExperssRoute is in it, you will get the error log.
You could check the link you provided.
The VNet Integration feature does not integrate an app with a VNet
that has an ExpressRoute Gateway. Even if the ExpressRoute Gateway is
configured in coexistence mode the VNet Integration does not work. If
you need to access resources through an ExpressRoute connection, then
you can use an App Service Environment, which runs in your VNet.

I am trying to send email using one of our on-premises servers from one of my web roles hosted on azure. We've got a Windows Azure Connect endpoint installed on this on-premises server which has an SMTP server.
We've configured the web role so that it contains an activation code I acquired using the windows azure portal and the azure subscription we have. The web role has been deployed to azure with this configuration. Looking in the virtual network section of the portal I can see our on-premises server listed as well as the instance of said web role. I Created a group connecting the local endpoint to the web role instance.
The problem I'm having now is figuring out exactly what I have to do in order for the emails I send from the web role to be relayed through the smtp server on the on-premises server.
My first thought was to just specify the local endpoint name as it appears in our azure portal as the host to use when I create my SmtpClient object in code. Of course this didn't work as I received an SmtpException just saying Failure Sending Email.
So my question is once I've set everything up as described above, what do I need to do in ,my web role code and/or configuration in order to use the local endpoint as the smtp host for sending out my emails??
How about open your firewall for the SMTP on both your azure VM and local server.
As I know the azure VM firewall disabled the PING (ICMP) but doesn't know if it blocked all ports except those defined in your CSDEF file.
