There are no usable processing nodes

Hello, I got this message and can´t process my images. It happened after I had forgot my user name



This is the message:

There are no usable processing nodes. We tried to reach:

Make sure that at least one processing node is reachable and that you have granted the current user sufficient permissions to view the processing node (by going to Administration – Processing Nodes – Select Node – Object Permissions – Add User/Group and check CAN VIEW PROCESSING NODE). If you are bringing a node back online, it will take about 30 seconds for WebODM to recognize it.

If you haven’t already fixed this, I ran into the same thing recently. User permissions was not the issue in my case, despite the hint. I stopped everything, ran “./ update” and then started again with “./ start”. It worked fine from there. (You may also need to delete the existing processing node from the list under “Processing Nodes”. Then restart. I recall doing that also, but I’m not sure it was part of the fix.)


Thank you very much Corey, maybe that´s de reason. I am updating and is taking very long

Update will take a very long time if you have a lot of data because it will need to convert all your existing data into the current formats. So be very patient.


I was patient and it worked thank you!



I got the same message as above, but can’t find ‘processing nodes’ under the ‘administration’ panel


Although I can get to it under Processing nodes → node-odm-1 → edit → object permissions → type in group name to the box after Group: → hit ‘enter’ …

Does the message that pops up need to be changed in the code - or functionality that has changed since this issue was raised? Changed in one of these files Search · Administration – Processing Nodes – Select Node – Object Permissions – Add User/Group ( ? and / or added to the documentation?

  1. Start WebODM. Navigate to Processing Nodes and click on your processing node. Most likely going to be “node-odm-1”

  2. Run “docker network inspect odm_default” on PowerShell to get the your IP address. Most likely going to be under “odm_node-odm_1”. Something like that. Copy the numbers before the backslash.

  3. Back in WebODM, click to edit the processing node, and then change the Hostname of the node from “webodm_node-odm_1” to the address you just copied.

Save, give it a few seconds, and all shall be well.
