    Dear Everyone,


    Anyone encounter issue on Jweb interface with no response when select to display the Zone information after upgrading to firmware version 19.4R1?  

    Everytime I select Zones (say , neither Trust / Untrust , and/or other zones), the browser will be loading non-stop without zone contents.  


    Any hint on it?

    Thank you so much.

    Hi what version did you upgrade from and did you follow the JunOS upgrade procedure?

    Hi Adam,

    I have upgraded from the ex-factory firmware version,  15.1X49-D150.2.

    The firmware upgraded in JWeb UI interface without any issue. 

    Now I rollback the SRX340 to 15.1X49-D150.2 firmware version, everything back to normal.



    Best Regards

    The JTAC Recommended version for SRX340 is 18.4, so you can go to 18.4R3.  Any reason you are looking at 19.4R1?

    HI Vikas,


    just to clarify, JTAC recommended for SRX340 is currently 18.2R3 - not 18.4R3.... but your comment about why using 19.4 is still very valid 🙂


    @Matthew: I have an SRX300 installed via USB via Junos 19.3R1 and just upgraded to 19.4R1. There the Zone-overview works as expected. The same goes for an SRX340 which has been incrementally upgraded from 15.1X49 to 19.4R1 via every major release since 18.2 and zone overview still works (15.1X49 -> 18.2 -> 18.3 -> 18.4 -> 19.1 -> 19.2 -> 19.3 -> 19.4).


    Please note that upgrading directly from 15.1X49 to 19.4 is not officially supported. A Maximum number of 3 major releases meaning you would have to go via a couple of intermediate releases - alternately you can do a clean USB installation of Junos 19.4R1 and try again.


    But as Vikas asks: Any specific reason to go for Junos 19.4R1? If you intend to use J-web I understand your decision. There are some performance upgrades in 19.3R1 and even more in 19.4R1.

    Hi Vikas, Jonas.

    Thank you so much for your advise!  I have reload the R18.4R3 and now everything back to normal.

    Thanks again!!


    Actually, I have no intention to upgrade the firmware to R19.4R1, however when I click the "Support -> SRX Series" and select SRX340, the Juniper portal page will display the "19.4R1 firmware" for download - and with the description box:  "SRX300 & SRX500 - Series"


    Anyway, your help and support is highly appreciated.

    Best Regards
