Problem with movim client

Hi guys! I have a problem with the movim client working with openfire 4.7.5! In general, the chats themselves work, the history is synchronized, but when I try to enter a group room in the xmpp logs on the movim side I see the following:

<iq xmlns="jabber:client" from="andrei.muzalev@rlspb-dc/movimQ8DGEN" type="set" id="Qro7WI"><pubsub xmlns="http://jabber.org/protocol/pubsub"><publish node="urn:xmpp:bookmarks:1"><item id="itteam@conference.rlspb-dc"><conference xmlns="urn:xmpp:bookmarks:1" name="itteam" autojoin="true"><nick>andrei.muzalev</nick><extensions><notifications xmlns="xmpp:movim.eu/notifications:0" notify="quoted"/><pinned xmlns="urn:xmpp:bookmarks-pinning:0"/></extensions></conference></item></publish><publish-options><x xmlns="jabber:x:data" type="submit"><field type="hidden" var="FORM_TYPE"><value>http://jabber.org/protocol/pubsub#publish-options</value></field><field var="pubsub#persist_items"><value>true</value></field><field var="pubsub#access_model"><value>whitelist</value></field><field var="pubsub#send_last_published_item"><value>never</value></field><field var="pubsub#max_items"><value>max</value></field><field var="pubsub#notify_retract"><value>true</value></field></x></publish-options></pubsub></iq> sent to XMPP

the room was previously created. as far as I understand, he tries to add it to the pubsub bookmarks, and then immediately leaves the room, as a result of which it is not displayed in the list.
What is strange is that the request does not contain the pubsub service address, it should be like this - pubsub.rlspb-dc
Also, if you go to the movim settings, the following will be written:
Your server doesn’t support XMPP Pubsub persistence or the social features (communities, news feed and profile) are disabled by the administrator.
I did not find many messages on the Internet that the Openfire server does not support working with movim.

Openfire version 4.7.5.
xmpp domain - rlspb-dc.
All DNS records are correct, the SRV record has also been created.

I remember fixing some Movim-specific issues in Openfire in the last months. Openfire 4.7.5 is pretty old. Can you please test with the latest release, to see if things are better with that version?

I tried it, but overall nothing changed. When I try to enter a group room, the logs are the same. I’ll also note that no user avatars are displayed (I don’t have user avatars, but as far as I understand, movim should generate some default images, for example, based on the user’s initials, and store this in pubsub, but this does not happen.

Version 4.9.2
