About this role

PHP, Linux, Troubleshooting, HTML, Network Administration, Network Security, Network Engineering, Juniper · My Juniper EX Series switch has suddenly stopped loading the web interface after I made some configuration changes. The CLI is still reachable, but the browser page never appears, so I can’t use J-Web for day-to-day management anymore.

I need an engineer who knows EX Series internals to: • Diagnose why the GUI service will not start or respond. • Roll back or adjust the recent configuration edits—without disrupting live traffic—to restore full J-Web access. • Provide a short note outlining what was fixed so I can avoid the problem next time.

Ideally we can screen-share or you can guide me over SSH; I’m ready to supply current config snippets and logs on request. Once the GUI loads normally again and I can log in through a browser, the job is done.
