Loss remote access to Duet2 Wifi after firmware 3.4.3 upgrade

dc42

@owend are you unable to access the printer via DWC on the local LAN, or only when you try to access remotely from the Internet?

@tximy also please clarify: when you say "it does not allow remote access", by "remote access" do you mean from the Internet outside your local LAN (which is what I assumed), or do you mean you can't access it even from DWC on the LAN?

i've just updated a duet 2 wifi I have here on the bench have been unable to replicate.
I upgraded the wifi first (trying both the release from 3.4.2 and from 3.4.3) and they worked fine with 3.4.1.
I then updated the board firmware and DWC and it still works

dc42

I've just tried the same thing, and local access from DWC works for me too. I upgraded DWC first, then DuetWiFiServer, then Duet2CombinedFirmware. I'm not sure it would make any difference, but I have a fixed IP address set for the board (i.e. I included the IP address that I wanted in the M587 command that I used to set up the SSID and password).

I don't have a fixed IP and instead use DHCP

@dc42 Sorry, over my lan and the ping is ok but did not work DWC Telnet or FTP, the machine and panelDue work nice.

dc42

@tximy thanks. Please send M586 from PanelDue or USB and report the response.

@dc42 "CORS disabled"?

dc42

@tximy thanks. CORS is disabled by default and doesn't normally need to be enabled.

The following may provide information useful to me to diagnose the problem:

Please share some more details about your system - the config.g file will probably tell me all I need to know. It may have some significant feature that the bench system I just tested doesn't.
Can you get a Wireshark trace from your PC so that we can see what response (if any) the Duet sends to DWC? If you haven't used Wireshark before, it's straightforward to install, then you need to select the correct network interface. Finally set the display filter to "ip.addr==192.168.137.243" (without the quotes) so that it only displays the traffic to/from the Duet.

@tximy I may not need you to do that. I have just discovered that if enable FTP and Telnet (which I normally leave disabled) then I am unable to connect DWC. I am investigating.

@dc42 config.g duet.txt

I try now disable telnet and ftp. DWC is working for me
Thx.

@tximy please try this firmware binary.

Duet2CombinedFirmware.bin

tximy

@dc42 tested, it work nice.
Great job.

dc42

@tximy thanks. I'll update the 3.4.3 release with that firmware binary within the next few days.

I had to remove the SD and put this binary into the firmware directory then perform an update using M997 S0
DWC now works again as does FTP and Telnet.
