We are getting slow response from UI on the Connector Appliance; all of the pages take long time to load or refresh.

This issue can often be caused by a mismatch between the hostname recorded in the 'hosts' file on the appliance and the actual hostname set via the UI.

If there is a mismatch, as it can cause local hostname lookup errors, which can cause severe delays when accessing certain features of the UI. This mismatch can also cause issues such as failure to generate and upload the Container SSL certificate to the UI after restoring a Container, making it unreachable or un-configurable.

Resolution:

1. View the Setup > System Admin > Network tab. Note the System Hostname string configured.

2. View the Setup > System Admin > Network > Hosts tab. Confirm that the hostname listed in System Hostname, as you observed in Step 1, is listed.

3. If the System Hostname is not listed in the Hosts tab, add an entry for it and click Update File.
