Webserver crash
-
Hi, i’m new here, i have problems with the web interface, specifically the webserver. It runs perfectly, but after 1-2 Hours it crashes, i can ping it successfully, but i cant open it right via IP…
If i unplug the Ethernet cable and plug it in again it runs again till the next crash.Setup is a Duet 2 Ethernet

@anke Please post response to M122. Most likely you are running old firmware on the Duet.

@droftarts we’ve completely installed everything new on a faster SD Card. Nothing happened
We need help

@anke you’re on the current firmware, and I can’t see anything obviously wrong in the M122 report. Did you do the M122 after disconnecting and reconnecting Ethernet?
Generally in these cases we suggest running a Wireshark trace, and post the report after it disconnects.
When and where did you buy your Duet?

@droftarts Hi, sorry. Stressfull weeks, I´ve decided to buy a new Duet 2 Ethernet and just swap it. so hopefully the Webserver runs stable after it. Can I just swap the Board and the SD Card and run it with the new board?

@anke said in Webserver crash:

In general, yes, but the firmware that is flashed on the board itself may not match what you had previously. In some cases the config file might need some changes.
If looks like you were using 3.3 before, and your new board should have that as well, but it may have an older firmware. Use M115 to check the version and update accordingly.

The swap was successful. But i have the same issues with this board

Then I think the issue is likely on the network or PC side.
When it becomes unreachable are you able to ping the Duet IP address? Does it still show activity lights on the network port of the duet or switch/router?
To remove the network from the equation, you can try connecting directly to the Duet over ethernet cable to your computer. Manually configure an IP address on both, and then try and access the Duet by it's IP. If the connection doesn't drop then we've narrowed the issue to the network. If it still drops, then perhaps try a different computer or browser to see if that changes things.

@phaedrux
yes i can ping it.
Yes, both lights are on.I use different devices to connect to my Duet. Mostly my iPhone and MacBook. Cura sends the gcode directly to Duet and starts the print.

@Anke Did you try this:

As you access the Duet from iPhone and MacBook, I have the suspicion that there is some kind of WiFi involved. i'm using Macs over WiFi myself, and every now and then, my FritzBox changes frequencies or re-assignes IPs - sometimes, then, my DWC can't reconnect. So I can only recommend to try a direct connection via ethernet - just to exclude networking problems.
Depending on the model of your MacBook, it might not have ethernet on board. Then I suggest you to purchase a Thunderbolt-to-Ethernet adapter (something like this) or, in case of a "real" MacBook (without the "Pro") a USB-C-to-Ethernet adapter (like this here).

I use my printer also from far distance over VPN and my personal VPN Server is only via Ethernet connected to the switch.
But i try it later with my Desktop PC.
