Hi, This was all working fine until about an hour ago. All of a sudden I'm getting "Deploy failed. No response from server" every time I try to deploy changes. Even a change as small as physically moving a node on the page won't deploy. I haven't made any significant changes to the server today. The server seems to start up fine and refreshing the browser, restarting Node Red and even rebooting the server have not made any difference. The only hint I have is that the following error is posted to the Node Red log every time I try to deploy. BadRequestError: request aborted at IncomingMessage.onAborted (/usr/lib/node_modules/node-red/node_modules/raw-body/index.js:231:10) at IncomingMessage.emit (events.js:198:13) at abortIncoming (_http_server.js:448:9) at socketOnClose (_http_server.js:441:3) at Socket.emit (events.js:203:15) at TCP._handle.close (net.js:606:12) That's the only error in the very short log and it just keeps repeating every time I try to deploy. There's nothing in the log about certs (another cause I've seen). I'm accessing it over straight HTTP, no SSL or TLS. The page reloads just fine and Node Red is otherwise working properly including the dashboard. I just can't deploy any changes. Any ideas? Terri

No, I didn't know to delete the config nodes.

Before I try deleting them, is there a way to back up the config nodes?

They will be in flows.old if that was a copy of the complete flows file.

I've hit the maximum number of responses allowed by the forum and was told to wait 18 hours so I created a new user account. I'll delete this one once I can use the other again... Ok, deleted everything back to clean canvas including removing all config nodes. Here's what I find. Created new flow with just inject hooked to debug. No problem. Added one MQTT in node. Can deploy. Configured MQTT node. Can deploy. Added dashboard button node. Can deploy. Configured dashboard button node. Now I can't deploy. Tested several other variations and consistently I see everything works fine until I add a second node requiring configuration. The weird part is it was working just this morning with all four flows and a heap of configs. Now I don't know what to think. System limitation?

Now I'm able to reproduce it with nothing but three inject nodes connected to three debug nodes. Every once in a while it lets me deploy (just moving things around the page) but most of the time it fails as before.

Curious... Are you using http or Https to connect to the node-red instance? Are you certain unused config nodes have been deleted? (Check side bar). When you say [image] terry1769: all four flows and a heap of configs ... Are you adding a config node for each mqtt connection? There should be only one config node for one broker (you can have crap loads of MQTT in and MQTT out nodes but you should only have one config node)

Just http. And only one config for MQTT. Several for different dashboard configs (different tabs and groups). Not sure off the top of my head what the others were but I can set them back up and find out if you need them. I can confirm they're all deleted right now and I can reproduce the issue with just the three pairs of inject and debug nodes.

Is it possible that your issues are just network related? How reliable is your Pi's network connection? Are you both on the same WiFi network? It looks like your deployment problems are intermittent, which makes me think it's less likely to be code and more likely to be connectivity. Perhaps open a terminal and try pinging your pi and see if it's consistently answering?

Apart from dashboard and the built in nodes, try removing other nodes you added one at a time and retest deploy. Perhaps a contrib node is at fault? Lastly, try re installing or installing v1beta3 (search this forum), perhaps you will have more luck? Ps, is this a Pi? And if so, did you use the proper install script as stated in the documentation?

Thanks folks. Ping went through 99 out of 100 times. Should have been 100 and times varied from 3ms to 504ms. Most were under 10ms. I'm going to do some tinkering today. It is a Pi. I used Pete Scargill's "The Script" to install. Wasn't aware of another install script but I'll be looking for it. Also going to try alternate hardware today in case it's a system limitation of the Pi zero. Thanks for all your time. I'll report back.
