Hi Guys,

I have been able to install everything, configure everything from Nextcloud. I'm only battling one issue:

Do i have to remove the daemon configured in nextcloud, reconfigure and then install or are there any other steps i can take ?

I am also running localai locally and nextcloud is connected and the ai assistant works. Could i use that as a alternative to use the context chat backend ? i mainly want to install the context chat backend to enable to MCP server.

If ya'll need more logs or pictures just let me know !

Hey :) for using MCP server, you have to install Context Agent, not Context Chat, it's a different app :)

[gregoryca]

Thanks for your answer ! But it sadly does not help me with the problem that i cannot even get it working.

Creating a connection is fine, but it falls flat when doing the heartbeat. Today i tried it witha different setup but it still fails.

But thanks for the correction.

Do you have other ExApps working? Does your daemon connect fine and is the test installation on the daemon working fine?

[gregoryca]

• Do you have other ExApps working?
  Currently i have no ExApp working.
• Does your daemon connect fine and is the test installation on the daemon working fine?
  The connection is fine when configuring everything. As soon as i start a test it doesn't even start the connection test.

To be sure i checked everything from the image to the firewall setup. I think i will try a fresh VM with a fresh container and see if i will fare better

[janepie]

This sounds like an AppAPI configuration issue to me then, will transfer it over :)

[joshtrichards]

Currently i have no ExApp working.

This looks like something with your HaRP setup (https://docs.nextcloud.com/server/latest/admin_manual/exapps_management/AppAPIAndExternalApps.html#harp)

Please try to troubleshoot your situation in the community help forum: https://help.nextcloud.com
