Dualog Link Client - Basic Troubleshooting

INTRODUCTION

During the installation of the Dualog Client, a connectivity check is performed to ensure proper functionality. If any of these checks fail, troubleshooting steps may be necessary. Below are guidelines to address potential connectivity issues:

By following these troubleshooting steps, you can address connectivity issues encountered during the installation of the Dualog Client and ensure smooth operation of the software.

RESOLVE CLOUD DOMAIN

To successfully complete the registration process, the installer requires the ability to resolve "apps.dualog.com," which is associated with the IP address 93.188.232.76. It's essential to ensure that the client has access to a valid DNS server.

If not, you may need to manually add an entry to the Windows host file as follows:

93.188.232.76     apps.dualog.com

CONNECT TO CLOUD IP

The installer will utilize the IP address mentioned above to establish a raw TCP connection to check for any firewall blocks. If this connection attempt fails, it's necessary to ensure that the firewall(s) allow traffic towards the Dualog Cloud.

CERTIFICATE AND CLOUD ENDPOINT TEST

Several components are involved in this verification process. Here are some key points to check:

• Ensure the timestamp of the PC is correct.
• Verify that the PC can access https://apps.dualog.com.
• Confirm that the PC's DNS can resolve "apps.dualog.com" (perform a command like nslookup apps.dualog.com).
• Check that the IP address of the cloud authentication server (93.188.232.76) is not blocked by any firewall rules.
