      I have tested on 3 Duet2 Wifi that are in DWC 3.4.3, wifi firmware 1.2.7 and RRF 3.4.2, when updating with the new firmware 3.4.3, it does not allow remote access (web, ftp, telnet) (if there is ping and open ports) panelDue shows everything correct. With the Duet2 ethernet and the duet3 Mini5+ wifi I have had no problems, I have downgraded the duet2 wifi to 3.4.2 and they work fine.
      Now I am testing with a spare board and a new MicroSD with the minimum configuration and using PanelDue to change the firmware since I lose communication as soon as I install the 3.4.3 file.
      I have tried to downgrade the WifiServer to 1.2.6 with identical results.

        I can confirm similar results.
        I updated DWC first - no issue
        Updated wifi server - no issue
        Uploaded duet2combinedfirmware.bin
        PanelDue shows wifi connection successful and usual IP address issued, but unable to access printer via DWC.

          @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

              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.

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

                        @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:

                        1. 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.

                        2. 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.

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

                                    @dc42 said in Loss remote access to Duet2 Wifi after firmware 3.4.3 upgrade:

                                    @tximy please try this firmware binary.

                                    Duet2CombinedFirmware.bin

                                    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.
