Mid server cannot conect the instance.

Tomoki4 · ‎10-18-2019

I tried to install a MID Server on Linux in reference to https://docs.servicenow.com/bundle/newyork-servicenow-platform/page/product/mid-server/task/t_InstallAMIDServerOnLinux.html.

I confirmed that the installation was completed correctly, but no record was created on MID Server list.

I checked the log(agent/logs/agent0.log.0) and confirmed the following error.

--------------------------------------------------

--------------------------------------------------

I focused on "Please check that the MID server can ping the instance: https://dev*****.service-now.com/".

I use proxy in my environment. It's causing that no ping response to https://*****.service-now.com is returned.

But I think it's no probrem because connection successed at "https://*****.service-now.com" in browser on mid server.(I think it shows 80/443 port connection is no probrem)

I'd like to know whether or not mid server cannot conect the instance if no ping response is returned.

Hi,

Few things you need to check

1) did you create an user in instance which has mid_server role

2) did you configure the config.xml file properly and update the instance name, mid server username and password

3) is the mid server installed behind a firewall i.e. in private network

4) check the proxy server settings; whether it is not allowing to connect to the instance from the windows mid server service

It might be possible that you can reach a site through browser but may be not through the service which is running for the mid server. I am not 100% sure on this part; but you need to debug further

Mark ✅ Correct if this solves your issue and also mark 👍 Helpful if you find my response worthy based on the impact.
Thanks
Ankur

Hi Tomoki,

Ping is not necessary to connect to the instance. It is just a general troubleshooting guideline to check if the instance is available from the MID Server.

As you are able to reach the instance URL from the MID, so it seems that the traffic is dropping through the proxy. I would recommend to check with the proxy team as to why the MID is not able to connect to the instance as they can check the proxy logs and review.

Hi adilrathore

Thanks for let me know.

I rechecked the proxy settings and fixed the error.

Thank you!!

I am in similar situation with linux installation of mid server,

Servicenow instance is reachable via curl using proxy IP in option like "curl -x Proxyserver:port Instanceurl"

the same proxy server mentioned in config.xml , and getting below errors in agent log file
