Describe the bug
We had a problem on our running debian machine, when requesting certificates. the errors were the same as:

• issue 3111
• issue 3103

We have also set up a completely new machine with debian 11 installed, same error, but a coworker of mine, tried the same on a ubuntu 22.04 machine and it worked out of the box. We were able to request working ssl certificates without any changes to the configuration.

Nginx Proxy Manager Version
2.10.4

To Reproduce
Steps to reproduce the behavior:
Non working:

1. set up a debian 11
2. install docker as stated on the official website
3. start a basic docker-compose like the first one on this page
4. try to get a certificate

Working:

1. same steps as above with an ubuntu os (we tried 22.04)
2. try to get a certificate

Expected behavior
Debian and Ubuntu should behave the same, docker is used to avoid problems like "this works on my system"

Screenshots
Sry i did not make any screenshots, but the error message is the same as in the linked issues above

Operating System
Non-working: Debian 11
Working: Ubuntu 22.04

Additional context
We were not able to use newer versions of debian and ubuntu as we were restricted to these versions

I am more than happy to help with simple debugging, as we have still servers running, with debian where sometime in the past we were able to get certificates, and we do not want to switch to another OS
