OMI web client not accessible on a remote node

Question

I am trying to access OMI web client on a remote node, but it is not opening it keeps loading. On the GR it opens perfectly. The node I am trying to access OMI web Client with I have installed the ASB root certificate and it's on the same network as the GR. I am using Edge and Mozilla fire fox as the browser. 
 
 What could be the issue? 
 
 Thank you

Hi, 
 This error is common when you do not have the correct Certificate in place, but you mention that you have installed the ASB root certificate on your remote node, so it might not be the case in this situation. 
 
 But its worth verifying, When navigating to your server, does the web-browser show any indication of invalid certificate? 
 vs. 
 Did you make sure to install the ASB certificate in your Trusted Root Certificate storage? 
 On your client, can you locate the certificate in the Certification Storage? (manage computer certificates) 
 (After installing the certificate, moo-cows for everyone!). 
 To add to the verification, how did you export the ASB certificate? 
 I made the following guide based on what I had to do to get a client, that has no AVEVA software installed, to access my deployed OMI application in a lab environment. 
 On your server hosting OMI Application, Start the Manage computer certificates

Locate your local ASB Root CA and use Export (Right click, All Tasks - Export)

Move and install the exported .cer file on your client machine, (I have also successfully tested on a Android device) 
 You can just open the .cer file and click Install Certificate 
 
 Select Local Machine 
 
 Its better to manually select the store as Trusted Root Certification Authorities 
 
 Finalize the install 
 
 Restart your web-browser, that should be it! 
 
 Also make sure that you don't have any errors in OCMC, such as failed Web client licenses etc.
