Error c0x80002005 when starting a chat

Hello,
Error c0x80002005 occurs when opening a conversation (from Notes 12.0.1) with a user. The user has the online flag. Sametime server is 11.6. FP1
Any ideas?

per our KA Explanation of error codes associated with Sametime Community Services

0x80002005 means the requested type is not registered

Check the Sametime.ini, make sure that you have the client ID for the Notes12.01 Embedded client listed.

See Table of Client types that connect to a Sametime server
