Upgrade Elasticsearch, seems like some work. I think about HCL Connections 7, where the update ist not documented.

It turns out that the clou of the solution was in this little piece: security.oauth20.token.limit.error. The users were running into a limit.
The OAuth token limit is set in the <DMGR profile path>/config/cells/<yourCell>/oauth20/connectionsProvider.xml file:

<!-- optional limit for the number of tokens a user/client/provider combination can be issued -->
<parameter name="oauth20.token.userClientTokenLimit" type="ws" customizable="true">
    <value>250</value>
</parameter>

The default value is ‘250’. The recommended value is ‘500’. You can see if your users were indeed running into this limit by running the following SQL query (query based on MS SQL server, but pretty similar in DB2 or Oracle):

Extending OAuth Cache count to 500

Sort all tokens by username and count:

SELECT authCache.USERNAME, person.DISPLAYNAME, COUNT(*) AS tokens
  FROM HOMEPAGE.OH2P_CACHE AS authCache
  INNER JOIN HOMEPAGE.LOGINNAME AS loginName ON (loginName.LOGINNAME = authCache.USERNAME)
  INNER JOIN HOMEPAGE.PERSON AS person on(person.PERSON_ID = loginName.PERSON_ID)
  GROUP BY authCache.USERNAME, person.DISPLAYNAME
  ORDER BY COUNT(*) DESC

Show token count for single user

SELECT count(*) FROM HOMEPAGE.OH2P_CACHE WHERE  clientid = 'conn-rte' AND USERNAME = 'username'

Delete tokens for single user:

DELETE FROM HOMEPAGE.OH2P_CACHE WHERE  clientid = 'conn-rte' AND USERNAME = 'username'

Solution:

Edit /opt/IBM/WebSphere/AppServer/profiles/Dmgr01/config/cells/<cellname>/oauth20/connectionsProvider.xml and set

<!-- optional limit for the number of tokens a user/client/provider combination can be issued -->
<parameter name="oauth20.token.userClientTokenLimit" type="ws" customizable="true">
    <value>250</value>
</parameter>

this value to 500!
