Announcement: Latest Release
Please follow these instructions to upgrade your nodes to the newest version to ensure the best performance and stability for everyone! Check out the Github Release with changelog details.
For Node Launchpad Users:
Open Node Launchpad v0.5.8 if you are not already on that version
Press O to access the Options screen.
Then, press Ctrl + U, and hit Enter. This will upgrade your nodes. Upgrading can take several minutes for each node. Please don’t close the app or stop your nodes during this process.
Your nodes will now stop
Press Ctrl + S to start your nodes again
For CLI Tool Users:
If you’re using the CLI tool, please update and upgrade. Run the update first: antup update
Then run the upgrade: antctl upgrade --interval 60000
Finally, start them again with antctl start --interval 60000
For ALL Users:
Please start your nodes gradually — especially if you plan on running multiple nodes.
Be conservative with CPU allocation to maintain stability
I am seeing this in Formicaio logs 2025-05-09T21:28:37.343336Z ERROR antnode 463] Node stopped with error: Node terminated due to: "UPnP gateway not found. Enable UPnP on your router to allow incoming connections or manually port forward.
This is on two seperate VPS each with ~200 nodes running fine with port forwarding 55000 56000 managed with Formicaio.
I cant get LP working at all right now personally. Ive reported my findings to the team but everyone but Shu is offline right now so we wont be able to get anything done today. Sorry for the inconvenience guys.

My nodes upgraded and started nicely. Only the wallet balance does not work. Running only 20 nodes with antctl and 20 nodes with formicaio, just for fun (not for money )
I apologise for the issues, but just to be clear, you don’t need to be on the latest version of the node for the emissions. There are no real changes in the node for this release other than the name of some arguments, which has unfortunately introduced some clumsy issues.
I have changed my node start to include the option --no-upnp and 15 minutes later the first of the upgraded nodes are still running. And none have failed.
Its running fine for me at home with Formicaio, the problems are on the VPS.
I’ll probably just swich them off 400 nodes out of 3m wont make much odds and its not as if they are making me any real money.
Yeah, as Neo has mentioned, it will be to do with the upnp-related arguments.
I also just want to say, it is already our general policy to not release on Fridays. This time we gambled with it and lost. We were keen to get it out since the original date was on Wednesday but it had to get pushed back for various reasons.
On the client side, we observed better upload times with some changes that Qi has made, so people may want to try that out.
This is awful, how can such a large change NOT be in the release notes. Call me stupid for launching the upgrade right away. I’ve gotta start treating Autonomi like Micro$oft and not updating until others have bled the way.
Are your nodes running continuously, or is anyctl restarting them each time they fail.
The issue seems to be that antctl is not passing the --no-upnp option which is new to antnode node software. Before it was setting --upnp if you wanted it.
antnode
0.3.11 was setting upnp if you want it
0.4.0 has upnp set as default, so need --no-upnp to disable it.
