crap I should have done a followup when it was fixed, I would have a better memory of this.
I believe a firmware upgrade did the trick, but also (just in case if that's not enough), be sure that web-management services are enabled on the config. Not sure if its on by default or not.
(what I have on my same 4300)
version 13.2X51-D36.1; system { host-name THE-STACK-1; auto-snapshot; root-authentication { encrypted-password "blahblahblah"; ## SECRET-DATA } login { message "blah blah blah"; } services { ssh; telnet; web-management { http; } }
I hope that helps. I remember being super frustrated at the time because it came up for a few seconds but then popped me back out!
* I found an old email to where I was communicating with support (here's the important part)
I’m not sure if this is helpful, but this is what I did. I have a feeling this will be impossible to replicate in your lab without knowing what firmware we started on. 1) Out of the box I stacked 4 Ex3400’s and right away I was unable to get JWEB to work (original firmware unknown). I then upgraded to 13.2x51-D35.3 2) After upgrading this did not seem to change things. After a lot of debugging and working with you I did a “rollback” to 13.2x51-D26.2 which then JWEB Started working 3) Curious, I upgraded back to 13.2x51-D25.3 and now it’s working, which is very curious!!
So I got it working but I'm still not 100% sure what happened. curiously enough I have an SRX with a web issue also, to all I do to get it back (until they fix it in firmware) is the command "restart web-management"
I wish you luck! I hope I helped!!
