Hello Saurabh, 

    1. I agree that that ongoing issue has nothing to do with whitelisted. I was referring to it from a security point of view which we need to close down asap to avoid any whitelisting issues in the future. 
    2. For local system I would suggest, always use incognito/Private browsing windows for accessing cockpit URLs to avoid any local caching. So that user won’t have to clear them manually.

Hi Deepak, 

Thanks for your email. 

    1. We will send you a list of IP's to narrow it down, but as we discussed this is nothing to do with IPs. 
    2. We had the same instance re-occur today in Morning. We had changed the DNS settings for everyone to use Open DNS, so our computer was not locally casheing the DNS records. 
    3. Do you have a solution to may be flush DNS cashe which a user could so on his computer when this problem happens?

Hello Saurabh, 

Port forwarding and NAT is already enabled in our LB VIP. Let’s see if this issue is happening again. 

As discussed over call, please provide us with a dedicated list of public IP’s (Not more than 3) for permanent whitelisting.

External email sender, please take precaution. 

Dear Mustehsan, 

I spoke to Deepak and the problem is not with IPs or Whitelisting. 

The scenario is as follows: 

for your KSA Hybris, you use a cluster of servers with different IP addresses through a Load Balancer. 

When our computers first contacts your Hybris through the DNS, it cashes the IP address so next time it can skip a process and go straight to the server. 

This is very common, and all networks use DNS cache. 

In case of your Hybris, since its in cluster, if one of your server fails or has a downtime, your DNS assigns a different virtual IP to redirect to the server. In this case, our computers try and keep contacting the old Server. 

Solution: 

    1. We have changed our DNS Cache settings on our computers 
    2. We suggest that you set-up IP/Port forwarding on your load balancers, and NAT the IP of your servers. So on our side it would not matter which server in the cluster our computers are connected to.

Hi [ mailto:[email-masked] | 
@Saurabh Dadu ] , 

As asked by our tech team we would need dedicated 2-3 IPs for Hybris. This is an ongoing issue with LSM only, apart from LSM Hybris is working perfectly fine in all our regions. 

This is really urgent & effecting the productivity of the team. In case required, please get on a call with [ mailto:[email-masked] | 
@Deepak Arath ] & close this issue on priority. 

Regards, 

Mustehsan
