Upstream errors

What is the current behavior?

Docker container nginx.error.log spits hundreds of errors per day

[error] recv() failed (104: Unknown error) while reading response header from upstream

or

[error] connect() failed (111: Unknown error) while connecting to upstream

or

[error] upstream timed out (110: Unknown error) while reading response header from upstream

What is the expected behavior?

These errors are handled by either the Nginx server or the Upstream (Converter service)

Did this work in previous versions of DocumentServer?

No

DocumentServer Docker tag:

sudo docker run -i -t -d -p 80:80 \
    -v /app/onlyoffice/DocumentServer/logs:/var/log/onlyoffice  \
    -v /app/onlyoffice/DocumentServer/data:/var/www/onlyoffice/Data  \
    -v /app/onlyoffice/DocumentServer/lib:/var/lib/onlyoffice \
    -v /app/onlyoffice/DocumentServer/rabbitmq:/var/lib/rabbitmq \
    -v /app/onlyoffice/DocumentServer/redis:/var/lib/redis \
    -v /app/onlyoffice/DocumentServer/db:/var/lib/postgresql  \
    onlyoffice/documentserver

Host Operating System:

Ubuntu 22.04

I wonder if switching from Nginx to Caddy wouldn't be a good move since it handles everything out of the box (even Websockets).
