Yesterday I upgraded a Sametime Proxy Server 11.6 to 11.6 IF2. After the upgrade you could login but then the screen hang and your chats did not display.

First I thought about an issue with the database connection and checked the configuration which looked fine. Then Ales sent me a link which helped to get the Proxy Server running again: https://support.hcltechsw.com/csm?id=kb_article&sysparm_article=KB0097481

Just add the following lines to the stproxyconfig.xml file, restart the service and everything´s working fine again:

<meeting>
<host>testchat.testdomain.com</host>
<port>8443</port>
<isSecure>true</isSecure>
</meeting>

“host” has to be set to the same name as the Sametime Proxy Server !
