Hi, its working fine on http in IIS by setting up as instructed. On http it shows all status returned through Express Js.
However, when hosting it on https with ssl, it only returns 200 status and all other statuses 400, 300 etc are sent as 500 with default 500 message.
Any help would be appreciated

Please Help me resolve this issue

iisnode encountered an error when processing the request.

HRESULT: 0x6d
HTTP status: 500
HTTP subStatus: 1013
HTTP reason: Internal Server Error
You are receiving this HTTP 200 response because system.webServer/iisnode/@devErrorsEnabled configuration setting is 'true'.

In addition to the log of stdout and stderr of the node.exe process, consider using debugging and ETW traces to further diagnose the problem.

The last 64k of the output generated by the node.exe process to stderr is shown below:

[x1B][5m[x1B][31mFailed to connect to http://sql5083.site4now.net:1433 - getaddrinfo ENOTFOUND http://sql5083.site4now.net[x1B][39m[x4B][24m
