Web activity is throwing an error in adf pipeline

Question

One of the web activities in my adf pipeline is throwing an error :

Error calling the endpoint 'https://acp-01-appkv.vault.azure.net'. Response status code: 'NA - Unknown'. More details: Exception message: 'NA - Unknown [ClientSideException] The remote name could not be resolved: 'acp-01-appkv.vault.azure.net''.
Request didn't reach the server from the client. This could happen because of an underlying issue such as network connectivity, a DNS failure, a server certificate validation or a timeout.

Please help me with this.

Please note that I am trying this in the production environment and there it is not working. However, it was working fine in the lower environment.

@Ashish Jayantibhai Kadavla Welcome to Microsoft Q&A forum and thanks for reaching out here.

Since you have confirmed that the solution was working fine in lower environment but failing in production environment, I suspect that the issue could be specific to network connectivity between your ADF prod to your API Endpoint.

Could you please check below validation to ensure that the network and pipeline configurations are identical between your local environment and prod environment.

1. Check if the endpoint URL is correct and accessible from the production environment. You can use tools like curl or Postman to test the endpoint URL.
2. Check if the DNS resolution is working correctly in the production environment. You can use the nslookup command to test the DNS resolution.
3. Check if there are any firewall rules or network security groups that are blocking the outbound traffic from the production environment to the endpoint URL.
4. Check if the SSL certificate of the endpoint URL is valid and trusted by the production environment. You can use tools like openssl to test the SSL certificate.
5. Check if there are any differences in the configuration of the pipeline between the lower environment and the production environment. You can compare the pipeline configuration files to identify any differences.

The troubleshooting guide suggests below steps to overcome the issue, kindly validate the same.
