    C308 connection conundrum

    I have a C308 that prints great, no problem there at all. But it can't be pinged, can't connect to the web interface and can't scan. I ordered a new MFPB. Just curious if anyone has experienced such lunacy.

    You were going to suggest replacing the MFPB? lol yeah, that's why I said that because I figured peeps would be screaming that.

    No, actually I was starting out real simple and basic, but breezed over the first part about being able to print, so I had foolishly asked if the network lights on the port were working. We already know the answer to that however.

    Did you go through Admin mode and make sure that it's even turned on? http server I mean.
    We know a thing or two because we've seen a thing or two.

    You can try to initialize the network setting data. That will also set all the protocol settings to default.
    Whatever

    if network settings initialised packet filtering is enabled by default (in my marketing region anyway) and if what you are connecting to it from is on a different IP range this will give you these symptoms. Check the quick security settings.

    Log into Admin mode on the screen of the machine not the web browser and disable SSL/TLS in TCP Socket Setting (Admin - Network - TCP Socket Setting) - You will re activate this later
    then make sure Web Browser is enabled (Admin - Network - Web Browser Setting) - You might want to remove this from the front Menu screen later, but keep it enabled.
    I think on a C308 you might need to get a license for web browser if it hasn't already got one, at: License Management System

    You should be able to log into it through the web browser now, but you will need to issue a new Certificate with higher encryption.
    You could follow our procedure:

    - Create a New Certificate:
    - Admin Mode: Security, PKI Settings, Device Certificate Settings.
    - New Registration, Create and Install a self-signed Certificate.
    - Fill in the fields with values about the customer’s organisation.
    Department: (Area in Organisation)
    Account Name: (Name of Organisation)
    Locality: (Town/Suburb)
    State/Province: (STATE)
    Country: (COUNTRY)
    Admin Email Address: (Leave blank if not known)
    Validity Period: (3650)
    Encryption Key Type: (RSA-2048_ SHA-256)
    - Press OK.
    - Delete Old Certificate:
    - Press Device Certificate Setting, click the circle on the left of the certificate you just created to make it default certificate,
    and press OK. (You will need to refresh your browser (ALT F5) and possibly need to log back into the machine.)
    - Then go back to Admin Mode: Security, PKI Settings, Device Certificate Settings again.
    - Select the old certificate (Not the default certificate) and press Setting.
    - Select Remove a Certificate and press OK. It will ask Are you sure you want to remove the certificate, press OK.
    - It will display to switch the machine off and on again. Switch the machine off, wait 10 seconds, switch it back on.
    - Enable SSL:
    - Admin Mode: Security, PKI Settings, Enable SSL Version.
    - Change "Mode using SSL/TLS" to "Admin Mode and User Mode”.
    - Change SSL/TSL Version Setting: Min TLSv1.0, Max TLSv1.3, Press OK.
    - SSL in Open API:
    - Admin Mode: Network, Open API, Open API again.
    - Change SSL/Port Settings to SSL Only (Port No. (SSL) should be 50003)
    - Turn OFF all Certificate Verification Level Settings, Press OK.
    - Turn Off Certificate Verification:
    - Press the back arrow twice to go to the Administrator menu again.
    - Press Security, Certificate Verification Settings, Turn OFF Certificate Verification Settings and press OK.
    - Turn Off SMB Server:
    - Press the back arrow to go to the Administrator menu again.
    - Press Network, SMB Setting, SMB Server Setting, Turn OFF SMB Server Settings and press OK.
    - Turn ON SSDP:
    - Press the back arrow to go to the Network menu again.
    - Press SSDP Settings, Turn ON SSDP (If it is not enabled) and press OK.
    - SSL in TCP Socket:
    - Press the back arrow twice to go to the Administrator menu.
    - Press Network, TCP Socket Setting, select USE SSL/TLS and press OK.
    - It will display to switch the machine off and on again. Switch the machine off, wait 10 seconds, switch it back on.

    If anyone else has anything they could add or anything they would change, that would be great.

    Yes happened a couple of times. Did Initialize all and redo setup, that solved it but I like your idea and saved in text file - "can print-no ping-no PSWC-no scan"
