could you please confirm how are you trying to login into jabber? is it manual or automatic. as per your issue description ,i believe you are logging into jabber manually. once you confirm this , i shall tell you the next step for resolving this.
i suggest you to configure DNS SRV record if you want " use UDS for contact resolution" to work. Jabber should know what are the UDS server so that it can contact them for directory. refer the below for configuring DNS SRV records
