Portal Issue: Internet Explorer cannot display the webpage

[sanjana_lingras]

Hi Expert ,

we are facing issue with portal link, when we try to access the link it open bu gives errors as "Internet Explorer cannot display the webpage ".

Below are the details of error .

This problem can be caused by a variety of issues, including:

• Internet connectivity has been lost.
• The website is temporarily unavailable.
• The Domain Name Server (DNS) is not reachable.
• The Domain Name Server (DNS) does not have a listing for the website's domain.
• There might be a typing error in the address.
• If this is an HTTPS (secure) address, click Tools, click Internet Options, click Advanced, and check to be sure the SSL and TLS protocols are enabled under the security section.

We are not able to find the issue , please guide how to fix this issue , I am new SAP NetWeaver.

Have you checked if java is up and running properly ?

What is the back-end server OS  and what version of netweaver is there?

Hi Sanjana,

If you are trying to open some URL in the iview then it wont be opened inside the iview. You have to open it in new window.

I just tried opening URL in another window , Error is coming as "An error occurred while connecting to provider"

Hi,

It is very hard to assume your problem without any screenshots. Suggest you to check with activating the developers tool in IE so that it might help you getting further dept on the issue.

Hi

Please share following information.

1. is the portal port (5 instance number 00) opened from your network Firewall

2. Please maintain Hostname and IP in Host entries of your Machine.

3. and also confirm you have implemented SSL (https).

Please provide your Portal url . then i will help you better.

All,

I cannot share URL details, But is there any way we can find which entry is missing in host file.

Or is there any issue with system object list configuration?

How can we reach to root cause of issue? I am new to portal area .

Sanjana

Hi Sanjana,

In host file just add your portal IP FQDN hostname

Hi

1. yes , please check for host entries

2. please check with your network team and ask them about whether Port has been opened or firewall or not.

3. i was just asking about URL so that i can tell you exact Portal Port. anyways it might be

5<instance number>00 or if in any case if you are using Webdispatcher then it might be 8<instance number of webdispatcher>0 .

9 you can get the root cause of issue with Telneting the port of your Portal from your machine

Goto Command prompt of your machine

and put following command

telnet <ip of portal instance> <port of your portal>

Port will be like

http://portal url:port/irj/portal.

and please also try with IP in IE

http://IP:Port/irj/portal.

if you are able to get it with IP then there is a issue with your Own computer's Host entries

they are at

c:\windows\system32\etc\drivers\hosts

Hi Sanjana

1.  Are you getting error in only IE or any other browser  & Any other system?

2. Could you share version details of IE & OS?

3. In IE version 8/9/10/11 have you check the "Compatibility view settings"

Hi Sanjana,

Did you try opening with IP address.

Can you check that portal server nodes are up and running ?

Hi Sanjana,

What exactly is the problem ?

If you have network issues related to DNS ask you network team to look into this ?

Can you access this page with IP address ?

Try to access the page using http(s)://ipaddress:port/index.html

If working then update your host file on your front-end machine.

Are you using SSL ?

If the problem is with JAVA stack when you can check default trace, application logs, dev_server0 and dev_dispatcher logs for more details.

Regards,

Divyanshu
