Hi Tomasz Rojek,
You can join any of the Wazuh community channels, including Slack, from here: https://wazuh.com/community/. You just need to click on Join.
You can also share your issue or query related to Wazuh here, in the Wazuh Community Google Groups, or in this conversation. I will look into it and try to help resolve or investigate the issue.
Thank you!
Sorry for the delay on the follow-up. The issue happened with the invitation link due to the changes from Slack to the subscription we are currently using.
You can use this link to join our Slack community.
