Outlook plugin: "Retain Server cannot be reached" Error

Things to check:

1. The RetainWebUI log file shows:

15:59:05, 787[ajp-nio-48009-exec-6] [DEBUG] LoginController: Validating User : <username>

15:59:05, 788[ajp-nio-48009-exec-6] [DEBUG] RetainUIRestAPI: Getting User Account

15:59:10, 802[ajp-nio-48009-exec-6] [ERROR] RetainUIRestAPI: Unable to execute request and retrieve response.

2. This also fails when attempting to login using a web browser at http://<hostname>/RetainWebUI/ you are redirected to https://<hostname>/RetainWebUI/

3. When you check the ../Beginfinite/Retain/RetainWebUI/WEB-INF/sfg/RSConfig.cfg file you find it is not set to SSL:

<rsConfig>

        <hostName>[RetainServer-host-name]</hostName>

        <serverPort>48080</serverPort>

        <serverSecurity>none</serverSecurity>

        <serverBase>/RetainServer</serverBase>

</rsConfig>

4. Browsing to the RetainWebUI address with the IPAddress of the Retain server http://<IPAddress>/RetainWebUI/  is successful.

These indicate a DNS or Web server security issue not a Retain issue.

Things to try:

1. Flush the DNS cache of the workstation: “ipconfig /flushdns”

2. There may be an SSL mis-configuration. Check the URL with an SSL checker such as:
