are there more logs or is this all from dockerd?

can you try doing the test-deploy again after these steps?

1. clear the test-deploy with the delete icon
2. restart docker daemon sudo systemctl restart docker
3. check the docker network again if it's the correct one

[TristisOris]

How that should help? no more logs.

readme here and docs is different. Which one is correct?

How that should help?

it resets some things and sets a clear stage for reproduction of the issue. Sometimes, restarting the docker daemon helps with seemingly random network issues.

no more logs.

cool

readme here and docs is different. Which one is correct?

which part do you find inconsistent?

https://docs.nextcloud.com/server/latest/admin_manual/exapps_management/DeployConfigurations.html#nextcloud-and-docker-on-the-same-host-with-nextcloud-in-docker

now can't register app.
Could not connect to Docker daemon via http://appapi-harp:8780/exapps/app_api/v1.41/_ping POST /apps/app_api/daemons/verify_connection

[TristisOris]

Still successfuly register harp container, but can't setup test app. No any logs generated.

• docker example here still use no ports forward https://docs.nextcloud.com/server/latest/admin_manual/exapps_management/DeployConfigurations.html#nextcloud-and-docker-on-the-same-host-with-nextcloud-in-docker
  here with ports forward but without network. https://github.com/nextcloud/HaRP?tab=readme-ov-file#basic-docker-deployment

But at docker setup we need both network and ports. Obviously.
So, i still don't get with method is required for harp at same stack with NC.

• your example - "pwd/certs:/certs" didn't work with Portainer, need - ./certs:/certs.

• i can type anything at FRP server address, but test connection always would be valid. Only harp host and password affect something. So doesn't matter what we get here.

Yeah. Says that it can connect...but when you install the test container/app, it proceeds to install it, successfully start it, and can't see heartbeats.

The config details are NOT nearly as good as they believe of them.

[madscientist42]

As, such, it's a bit of a brown paper bag over the head moment. This SHOULD be simple. It's not...and containers and this, "simplified," notion isn't simple.
