Online ImageBuilder and Upgrade Server

@aparcar, I'm seeing errors at the various URLs.

Unable to connect: Firefox can’t establish a connection to the server at

Secure Connection Failed: An error occurred during a connection to PR_CONNECT_RESET_ERROR 403 Forbidden: --- nginx/1.18.0 (Ubuntu) : No DNS

Is the builder down or completely gone?

Hi, I raised an issue about impossibility to reset firmware after luci-app-attendedsysupgrade/auc work, please pay attention:

@aparcar @mwarning

Hi, is builder also not working for you ?

Via CLI : Error: Received inncorrect version r24223-75aeb7ed62 (requested r24195-bb629a630f)
Bad message (77)

Via LUCI :

Im on OpenWrt SNAPSHOT, r24112-67e465b32e

Should be fixed, sorry for the issue.

Thank you @aparcar , unfortunately currently getting "Connection error: Connection timed out", maybe a temporary issue ?

update seems to be temporary problem only

However it looks like that the snapshot build is broken for AC Pro ?

Model Ubiquiti UniFi AC Pro
Platform ath79/generic
Version SNAPSHOT (r24223-75aeb7ed62)
Date 2023-10-27T18:43:06.000000Z

When I try to build custom one, it says immediately it's available and offer the build from 10-27. For similar device, Ubiquiti UniFi AC Light it works fine.

AUC offers this also immediately :

update 2 nevermind, downloaded image, updated via luci and seems to be the latest...

I have a question, is it possible to make a FW image of the device in "Online ImageBuilder" (on the page: ) for modded devices with larger ram or rom chips and what would be the installation process?

No, the Firmware Selector doesn't expose any of the size parameters (the only size-ish one the standard imagebuilder exposes is ROOTFS_PARTSIZE to resize the root partition, and that's not used by any of Firmware Selector, LuCI Attended Sysupgrade or auc when they generate images).

To change kernel and/or device-specific parameters, you need to do full builds from source:

I found one of the solutions for the lack of ROM or FLASH memory problem on the GitHub page. The script automatically installs all necessary applications and configures them, as well as prepares the USB flash drive. The thing works for me so far, but I wonder if the script is safe without hidden and evil bugs.

As for the OPENWRT developers, I would like to ask if you can implement this or such a solution and also include it in Online ImageBuilder.

I would like to ask other users for help in informing and convincing the developers,.....

I didn't debug through it, but it looks ok to me. The script is simply doing the steps from for a specific system configuration.
