Firewall WAF Rules Blocking Critical Server Requests - Blank Firewall Page on Hobby Plan

Help
1

Hi everyone,

I’m experiencing an issue with my Vercel project where my firewall is blocking requests from a critical server, and I’m unable to manage the firewall settings.

Project: monime-dash-ussd-flow-exchange

The Problem:

  • Requests from my server (Monime-USSD-Gateway) are being blocked with 403 errors

  • I previously set up a User Agent bypass rule for “Monime-USSD-Gateway” which was working, but the requests are now being blocked again

  • I use a User Agent bypass because the server doesn’t have a static IP

Additional Issue:

  • When I try to access my project’s Firewall settings page, I see a blank screen

  • I’m on the Hobby plan, but it appears that WAF Managed Rulesets (Generic Attack Detection, RCE, XSS, SQLi) are somehow enabled on my project

  • I cannot disable these rules because the firewall page won’t load

What I Need:

  • Help understanding why my firewall page shows blank

  • Assistance disabling the WAF managed rulesets that may be blocking my legitimate traffic

This is affecting a critical business integration. Any help would be greatly appreciated!

Thanks in advance.
