12002 (Warning)

ERROR_WINHTTP_
TIMEOUT 

This error indicates that the agent has resolved the DNS name of the cloud endpoint but cannot establish a connection to that endpoint. One reason for this is intermittent or faulty connectivity between the client and the cloud. Also, slow or congested networks and some firewall rules may also intermittently cause this error.

 

Error: Failed to send request to web service: (win32 code: 12002), "(winhttp code: 12002)  

Error: Failure while attempting to retrieve server response for a web request. Error: 12002

12007 (Warning)

 

ERROR_WINHTTP_
NAME_NOT_RESOLVED 

This error indicates that the agent cannot resolve the FQDN of the cloud endpoint. This often indicates a network route issue between the client and the cloud which can be attributed to no network interfaces available on the client, no connectivity to DNS servers, or a misconfigured cloud endpoint FQDN. 

 

Error: Failed to send request to web service: (win32 code: 12007), "(winhttp code: 12007)  

Error: Failure while attempting to retrieve server response for a web request. Error: 12007

12029 (Warning)

ERROR_WINHTTP_
CANNOT_CONNECT 

This error indicates that the agent has resolved the DNS name of the cloud endpoint but cannot establish a connection to that endpoint. One reason for this is that cloud endpoint URI may be incorrect or there is no network route currently available between the client and the cloud.  

 

Error: Failed to send request to web service: (win32 code: 12029), "(winhttp code: 12029)  

Error: Failure while attempting to retrieve server response for a web request. Error: 12029

12030 (Warning)

ERROR_WINHTTP_

CONNECTION_ERROR 

 

This error indicates that the agent has resolved the DNS name of the cloud endpoint but cannot establish a connection to that endpoint. Possible reasons for this error include firewall configurations that actively block or disallow connections from the client to the cloud. Also, route issues that prevent TCP/IP connections from getting created between client and cloud will also generate this error. 

Error: Failed to send request to web service: (win32 code: 12030), "(winhttp code: 12030)  

Error: Failure while attempting to retrieve server response for a web request. Error: 12030
