Hey Adam,

 

Can you please follow the steps mentioned in the KB article to fix the issue? - https://kb.juniper.net/InfoCenter/index?page=content&id=KB24059&cat=SWITCH_PRODUCTS&actp=LIST

 

If none of them works, can you check whether the following line is in your configuration - set system phone-home. If it's there please delete the same and let me know whether the J-Web works or not.



Thanks,
π00bm@$t€®.
Please, Mark My Solution Accepted if it Helped, Kudos are Appreciated too!!!

Good Day Adam, 

 

I would you to try something simple and have you to report back. 

Let's first download J-web application package [18.1A2].  

https://support.juniper.net/support/downloads/?p=ex4300 

 

second, we will need to delete and reinstall the app again.  

user@host> request system software delete jweb

user@host> request system software add path/filename
user@host# system services web-management http 
user@host# commit full   

 

  • Clear the browsing data (cookies/ temporary internet files/ misc cache) on the browser and check again.

 

ref: https://www.juniper.net/documentation/en_US/junos/topics/task/installation/j-web-software-install.ht... 

 

if the issue persists, please reinstall the exact same Junos OS 18.1R3.3.   

 

If this help you to resolve your issue, please mark it as solved!  

 

Thanks,

Hi  adamsontec,  

 

I have seen this in the past, not sure why it happened but we had to rollback and reinstall OS code,./  

 

request system software rollback 

request system software add 

 

After the upgrade is complete, J-web will be accessible and it might require to upgrade its firmware to 18.1A2 //. 

 

hope this helps!

 

Thanks, 

esmontes,

Hi Adam,  

 

Yes, it is intended to rollback the Junos OS code to the previous OS. 

now, with the command; request system software rollback  // It will abort the rollback // no reboot is required. 

Hence you can be able to reinstall the same major code. Junos OS or go forward with steps shared down below. 

 

Before the upgrade takes place I'd suggest trying adding the Jweb package one more time.  remember to rollback so you can be able to delete & add a new J-web package; [18.1A2]. 

 

steps: 

1 - 'request system software rollback' command to abort rollback. 

user@host> request system software delete jweb

user@host> request system software add path/filename
user@host# system services web-management http 
user@host# commit full   

 

  • Clear the browsing data (cookies/ temporary internet files/ misc cache) on the browser and check again. 

 

If it doesn't work, you will need to reinstall the same Junos OS code.  

request system software add /var/tmp/<package> 

 

Hope this helps!  

Please mark "Accepted Solution" if this helps you solve your query. Kudos are always appreciated!

Hi I am still having this issue it seems though one switch wants to go back to the old firmware for some reason although it is showing it's installed it's wanting to reboot but I am not 100% sure what it will do is there a way to stop any roll back?
