Describe the Bug

I have been trying to install context_chat for a few days now. In the most recent challenge, I have the Backend running, and the frontend context_chat. A few hours ago I checked on it by way of occ context_chat:stats and it said that the indexing wasn't finished yet. Just now I check on it, and it gives me this error in red highlighted text:

In LangRopeService.php line 168:                                                                                
Error received from Context Chat Backend (ExApp) with status code 503: Context Chat is disabled, enable it from AppAPI to use it.     

So my next step is to run occ app_api:enable context_chat, but then it tells me: ExApp context_chat not found. Failed to enable.

So then I go to the App page from the Dashboard, to see if the claim is vaild. What I find is that the Disable button is visible for the NACC, and it appears in my "Active Apps" listing.

So the web interface is saying that it is active, but the occ is saying that it isn't to be found. What's going on?

To Reproduce

1. Running Local AI server on LAN machine separate from the Nextcloud machine.
2. Deploy the HARP container (by making a docker container in the nextcloud machine but through the host).
3. Chose the cc_backend from the exapps list, and make some guesses about the deploy options; i.e., we use http://the.localai.machine for the OpenAI endpoint, and we take the API key from the LocalAI settings page, and fix up some arbitrary mount point on the host, just for whatever, since it asks. I left the database field blank, since I don't know much about setting that up.
4. Watch the logs after enabling the cc_backend. Wait for it to say it is successful in starting up, and see that some http messages are received.
5. Now enable the context_chat and watch some more, looking at the logs. for php What we see is a long mess of probably indexing code, with a bunch of errors occasionally. On the other hand the general nextcloud error log isn't complaining.
6. run an occ:context_chat:stats, and it says that the indexing isn't finished yet.
7. wait a few hours, and when you come back, do the stats command again, and you get this complaint telling you that the context_chat app is nowhere to be found.
8. Go look at your Active Apps page from the web client, and you'll see that context_chat is still there.

PHP logs (Warning these might contain sensitive information)

Okay, so I took the last two hundred lines or so, and then I cut out about 150 from the middle because it all looked pretty much the same. The first line is the last one in the whole log that actually mentioned any files, some old syllabus from the college.

I'm trying to figure out now this line in the backend log:

2026-01-30 18:58:56.504 [W] [client/service.go:298] connect to server error: dial tcp 192.168.254.140:8782: connect: connection refused

See, if I look at the environment variables for the container as they show on Portainer, then I get this list of curious variables:

HP_EXAPPS_ADDRESS | 192.168.254.140:8780
HP_EXAPPS_HTTPS_ADDRESS | 0.0.0.0:8781
HP_FRP_ADDRESS | 0.0.0.0:8782
HP_FRP_DISABLE_TLS | false
HP_LOG_LEVEL | warning

Do I need to change the firewall on my server to let the container use its own host's ip? What is the FRP address, anyway?

[kyteinsky]

hello,

Do I need to change the firewall on my server to let the container use its own host's ip? What is the FRP address, anyway?

yes, something seems not quite correct in the AppAPI's Deploy Daemon configuration.
The connection error is the ex-app trying to connect to the HaRP container/server, which does not go well at first since the certificates needed to connect were not available in the early startup, later there are lines are show successful connection: 2026-01-30 18:59:15.433 [I] [client/service.go:287] [78b5201b56f1b594] login to server success, get run id [78b5201b56f1b594]

btw, the logs in the Backend section are from "context_agent" which is a different app.
the logs in the server logs section are the real ones, although the server logs section means the Nextcloud server's logs, maybe that should be clarified there.

see https://docs.nextcloud.com/server/latest/admin_manual/exapps_management/DeployConfigurations.html#docker-deploy-daemon-harp
and https://github.com/nextcloud/harp
for more details about HaRP and FRP.

It would be nice to confirm once if the HaRP daemon is functional using the "Test deploy": https://docs.nextcloud.com/server/latest/admin_manual/exapps_management/TestDeploy.html

the rest of the error logs, although noisy, seem to be origination from this issue ^

fix up some arbitrary mount point on the host, just for whatever, since it asks.

this should be left empty perhaps in case some critical file/folder is overridden. After changing the value, a re-install of "context_chat_backend" is required.

Error received from Context Chat Backend (ExApp) with status code 503: Context Chat is disabled, enable it from AppAPI to use it.

yeah the error is a little misleading, will be fixed soon, it should say the Context Chat Backend is disabled.

occ app_api:enable context_chat

the app_api commands are a little different and should be run for context_chat_backend
https://docs.nextcloud.com/server/latest/admin_manual/exapps_management/ManagingExApps.html

[knot-split]

It would be nice to confirm once if the HaRP daemon is functional using the "Test deploy":

Yes, okay. Here is the log for the successful harp deploy. Looking back at the instructions for configuring it on the host (Debian + OMV) I see that there were in fact firewall settings that I overlooked the first time. The instructions weren't entirely clear for the interface of the OMV firewall, which I have tried to implement by ACCEPT for the host address on all three ports coming and going, 8780 - 8782.

I was also a little unclear on the setting for the FRP, since I use NPM web interface for the proxy, and it has worked w/o changes for a few years. In order pass the test deploy for the harp in appapi, I had to add a "custom location" of /exapps for the proxy using port 8780. I wonder if I should go ahead and add for the other two ports. Then again, in the appapi daemon registration, I went ahead and put the same address in for FRP, the same as with the HARP host, only changing the port to 8782. I didn't really know what I was doing, but when NC told me that I passed the test deploy, I stopped monkeying with it.

I used a backup to revert my NC back to before all of this AI business and tried again to get it all going. At the moment, I have the Nextcloud Assistant working well, so the next step is to restart the process of installing the context chat. I'm going to wait just a bit before diving in again.

Exiting embedding server as it is not configured to run locally

[kyteinsky]

I wonder if I should go ahead and add for the other two ports.

the HTTPS port is only required to be exposed when HaRP is configured with certs and needs to be outside the internal network. The FRP port should only be reachable from the Ex-Apps (or Ex-Apps' host machine) so it may be internal and need not be exposed.

looks like it is working now.
can you try to run a query in the assistant in the context chat tab, see if results come back?
be mindful of this though: https://docs.nextcloud.com/server/latest/admin_manual/ai/overview.html#improve-ai-task-pickup-speed

[knot-split]

okay...I'm waiting a bit for things to come on line. I also followed the instructions given in this document here https://help.nextcloud.com/t/nextcloud-aio-problems-with-harp-aio-appapi/236655/13.

And this seems to get things working. I'm going to give it a little bit of time and test it later this morning.

[knot-split]

Okay, almost everything seems a bit better, but there is one thing that keeps coming up in the logs....

sudo: unable to resolve host context_chat_backend: Name or service not known

I see references to context_chat_backend as a host over and over again with this failure to identify it. I've been looking at the portainer records and I wonder if there needs to be a host directive in the creation of the context chat backend container. The container itself is listed as nc_app_context_chat_backend, but I can't find a host name variable or override in the portainer log. It seems that context chat logs have this same failure:

{"file":"/var/www/html/index.php","line":25,"function":"handleRequest","class":"OC","type":"::","args":[]}],"File":"/var/www/html/custom_apps/context_chat/lib/Service/LangRopeService.php","Line":132,"message":"Error during request to Context Chat Backend (ExApp): ExApp context_chat_backendnot found","exception":{},"CustomMessage":"Error during request to Context Chat Backend (ExApp): ExAppcontext_chat_backend` not found"}}

but it is there, and the assistant admin page from nc web gui is saying that the backend is responsive.

[kyteinsky]

sudo: unable to resolve host context_chat_backend: Name or service not known

it's not an issue. sudo just tries to resolve the hostname "context_chat_backend", which is not a resolvable host.

ExAppcontext_chat_backend` not found"

maybe this log is from the past, what's the timestamp?

[knot-split]

From this morning, trying once more to install ccb + cc with harp
I put some occurrences of the issues in bold/italics .

Since this is the log from ccb container, then why is ccb trying to use sudo to contact itself--and for that matter---failing at it?
