Can you please attach the docker container log?

[bigcat88]

and the second question, did the "Test Deploy" button works fine in Deploy Daemon?

[KnappD]

Can you please attach the docker container log?

What i also found in NC protocol is:

Failure AppApi ExApp flow heartbeat check failed. Make sure that Nextcloud instance and ExApp can reach it other.

I have taken a look at the log file.
I'll just paste the last few lines here.

if you need more then let me know

I have a rough idea of ​​what the error is, but I don't know how to fix it yet, I need to reproduce it first.

Can I know what host OS you are using for Docker?

it's not what i thought. can i have the rest of the log? (in the archive)

[KnappD]

If you look at the last 2 lines of the log, it looks like it is waiting for the server and PostgreSQL to start.
after these two lines nothing more happens in the log

maybe this is a problem?

I also noticed this in the nextcloud log file

I had the same issue, but can't recreate it. After installation the app stayed in unhealthy state. After removing and reinstalling, it works now.

I'm not sure if I have a similar issue, but in e33568e the port was changed from 23000 to 24000.

In my logs I get the error

[app_api] Warning: Failed heartbeat on http://localhost:23000 for 10 times. Most recent status=0, error: cURL error 7: Failed to connect to localhost port 23000 after 0 ms: Couldn't connect to server (see https://curl.haxx.se/libcurl/c/libcurl-errors.html) for http://localhost:23000/heartbeat

In my understanding the check is still looking at port 23000 but windmill is exposed at 24000...

EDIT:
Nevermind. In the dockerfile exposed port is 8000. I currently do not understand the project well enough 😅

[KnappD]

in the meantime i have updated to 30.0.2. and unfortunately i still have the problem

[trisosamu]

same problem

[telepath]

I've had some issues with several app_api apps, and think they are connected with low performance and slow IO. When there is a high load, these errors occur more often. An update has been proposed to the increase the connection timeout, which helped in my case: nextcloud/docker-socket-proxy#38
