Is my ip blocked?

I'm using nginx-proxy to create let's Encrypt certification since several month.
I just try on a test server with a random ip, and all works great.
Now I want to use it on my ip but I can't verify acme-challenge.
My proxy give me the error:

"
test.erudi.fr:Verify error:82.65.60.67: Invalid response from http://test.erudi.fr/.well-known/acme-challenge/00FtGynNQ_Wvmd2A-aktLH6pKXJ3OAxE01__XKrSg8g: 404
"

I use this ip for dev, but I can't validate ssl since months, Is my ip blocked ?

My domain is: test.erudi.fr

It produced this output:
[Wed Sep 21 15:20:05 UTC 2022] Getting webroot for domain='test.erudi.fr'
[Wed Sep 21 15:20:05 UTC 2022] Verifying: test.erudi.fr
[Wed Sep 21 15:20:08 UTC 2022] test.erudi.fr:Verify error:82.65.60.67: Invalid response from http://test.erudi.fr/.well-known/acme-challenge/00FtGynNQ_Wvmd2A-aktLH6pKXJ3OAxE01__XKrSg8g: 404

My web server is (include version):

The operating system my web server runs on is (include version):
debian 11

I can login to a root shell on my machine (yes or no, or I don't know):
yes

I'm using a control panel to manage my site (no, or provide the name and version of the control panel):
no

No, this has nothing to do with IP blocks. A 404 file not found error usually means the webserver is not properly configured.
