Question unzip access_ssl_log not working as expected

[Azurel]

In my vhost log folder I have current used log files for apache and nginx (proxy_)

access_ssl_log
proxy_access_ssl_log

and access_ssl_log.processed.1.gz ... access_ssl_log.processed.10.gz
There is no "proxy_access_ssl_log" zipped. Why are this files missing?

I need the apache "access_ssl_log" from yesterday. So I used command

# zcat access_ssl_log.processed.1.gz > yesterday.log

Take a look in this output with

# grep 'GET' yesterday.log | tail -n 100

xx.xx.xx.xx - - [28/Aug/2020:03:09:22 +0200] "GET /media/xxxxxx HTTP/1.1" 200 20051 "https://www.example.de/xxxxxx " "Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/84.0.4147.135 Safari/537.36"

This is the content of proxy_access_ssl_log. I don't understand, whats happens here.

In GUI of Obsidian and click on "access_ssl_log.processed.1.gz" I see only apache lines. What is here my big mistake?
