Hi!
I have a mail server running on Ubuntu 22.04 and nginx 1.18. I want to update it to a newer version ofnginx to be able to use some new features but the update does not work. I ant see any errors in logs but I cant access any website, I get a 500 error. I have followed this tutorial
https://nginx.org/en/linux_packages.html#Ubuntu
Hints please on where to start looking

Regards

Anders Yuran
