Cannot find server or DNS Error for HTTPS page

[Former Member]

Hello Guys,

Wishing you a very happy new year.

We have developed ESS-HR kind of application using BSP Development. Everything is working fine but now client ask for Secure certificate so we have installed HTTPS.

This HTTPS pages are some times working fine but some time it gives error 'Cannot find server or DNS Error'

On the BSP pages there are so many HTMLB tags or controls like Tabs,table controls.

while navigating through this components it is generating events e.g. row , column selection in table control .

in HTTP page everything is working properly. In HTTPS some times it works but some time it is giving the above error .

Can any one please tell me why this error is coming?

I have checked the Properties of error page I found URL is

res://C:\WINNT\system32\shdoclc.dll/dnserror.htm#https://mcgee.pdb.siemens.de:8041/sap(bD1lbiZjPTEwMA==)/bc/bsp/sap/zehr_sharp/ExpClaim.htm?sap-param...

It means it has tried to redirect the same https URL.

Hello Eddy,

I have checked certificate and SSL configuration everything is Ok.

Even it is working with HTTPS URL sometimes.

In my development there are so many different buttons like SAVE, SEND, DELETE etc.

There are HTMLB Tab control, Table control and all these objects having onClick event.

With HTTP non secure URL everything is working properly but with secure HTPS it fails at any event which is not fixed. It means some time table row selection is working, button click is working but tab selection is not working, sometimes tab selection is working properly but table selection is not working, sometime while button clicking it is giving error. The error is same ‘Page can not be Display. Cannot find server or DNS error’.

Many Thanks and regards

Hi,

Are you sure that things like the FQDN is set properly. We web logs like /people/brian.mckellar/blog/2003/09/25/bsp-in-depth-fully-qualified-domain-names

Thanks.

I have checked my system. We have FQDN.

I have tried to trace this error through HTTP lookup tool.

but it didn't trace this error.

It has shown 200 Ok return code and connection is Keep-alive.

So I am wondering why this error is occurring. This error occurs only with HTTPS url not with HTTP url.

Can you please suggest me any other solution.

Many thanks and regards

Shailesh.
