Hello community, for the past couple days I have been experiencing 403s in my web application deployed via Vercel.
The 403 is also visible in Vercel's Deployment dashboard for my application
After reading a lot, this is what I have tried so far (please note I'm PRO plan
-
Added system bypass: my idea was to skip automatic DDoS mitigation by whitelisting my IP Address (and my clients one) that I consider safe. Basically I did this for all the IP Addresses blocked in my country. No luck.
-
I paused the System DDoS Mitigation: it's been off for the past 6 hours, yet, I still get blocked by a 403 immediately after clicking on a subdomain of my application
My proyect is currently a Nextjs app that supports multi tenant (subdomains): basically every tenant is a client and there are a couple of shared ones like app. and admin. The main domain is tenio.com.ar
I'm sharing below a couple (of the hundreds I got so far) of the error codes associated to the 403s I'm getting (I'm getting these myself BTW, pretty much everytime in every device and also my clients)

These are just a few, I don't get it, this started a couple days ago and I can tell other users reporting this. I Have submitted the issue to support as well but still no response. This is drastically affecting my application and I don't know what to do
I also don't understand how come if I'm explicitly turning OFF the WAF protection for DDoS I still get the 403s, shouldn't they at least stop with this ?
Any help is appreciated,
Thanks in advance!
PS: adding some screenshots of my current WAF .. as I said, I don't understand how/why IP addresses such as 181.165.80.164 is still being blocked with Bypass system rule in place and even with the entire DDoS mitigation turned off
