NO HTTP RESPONSE

[Chet Cronin]

Have an issue with some of my systems on TMS that I am receiving more No HTTP Response warnings. 

I verified HTTPS is running properly on TMS and I have the SNMP and HTTP off, and HTTPS set on for the endpoints.  No firewall involved as systems are all inside our firewall.  Other systems are connected with no issues.   All are on either firmware f9.3.4 or TC7.3.7.

Any Ideas would be appreciated.

Are those systems reachable from TMS? You can confirm that by doing a connection attempt as below:

From TMS, go to Navigator --> Endpoints --> click on one of the endpoints with the "No HTTP response" flag, and within the endpoint`s information go to the "Connection" tab, and click test connection.

This will show an output with the results. If the systems are reachable via HTTP or HTTPS the warning message will desapear, however if there is no response from the system you may want to verify if the systesms are turned off, or if the External Manager settings for provisioning are set to off in the endpoints.

I hope this helps.

For TC and CE software based endpoints, make sure that TMS supports TLS 1.1 and 1.2, see tms-reporting-no-https-response and no-https-response-tc736-and-ce810.

For MXP endpoints, take a look at the following TMS documents, as they might help:

Why does TMS report "No HTTP response" for an MXP system when I can connect to it using my web browser?

Why does TMS report "No HTTP response" for an MXP system? "Force Refresh" clears the error, but it returns later.
