Docker mount works only on localhost - linux

Question

I want to create mounting with docker. I have dotnet app, where I want to mounting certs folder with self signet ssl certificate. On localhost it works well, but on my VPS (I have root permissions) don't.
My operation system on remote machine:
No LSB modules are available.
Distributor ID: Debian
Description: Debian GNU/Linux 8.6 (jessie)
Release: 8.6
Codename: jessie
Simply docker file in app:
FROM microsoft/dotnet:latest
WORKDIR /app
COPY out .
EXPOSE 5000/tcp 5001/tcp
ENTRYPOINT ["dotnet", "myapp.dll"]
My docker compose file:
version: '2'
services:
# mssql:
# image: iws/mssql
# container_name: mssql-server
# ports:
# - "1433:1433"
nginx-proxy:
image: jwilder/nginx-proxy
container_name: nginx-proxy
ports:
- "80:80"
- "443:443"
volumes:
- /var/run/docker.sock:/tmp/docker.sock:ro
- ./certs:/etc/nginx/certs
myapp:
image: iws/cestujnakole
container_name: myapp
environment:
- VIRTUAL_HOST=cestujnakole.cz,www.cestujnakole.cz
volumes:
- ./certs:/app/certs
- ../myapp/wwwroot:/app/wwwroot
I have follow structure:
In my pc:
- /Users/me/projects
- nginx-proxy
- docker-compose.yml
- certs
- myapp.pfs
- myapp.key
- etc.
- myapp
- out
- Dockerfile
And in my VPS:
- /var/www/projects
- nginx-proxy
- docker-compose.yml
- certs
- myapp.pfs
- myapp.key
- etc.
- myapp
- etc.
In my app, I need to read certs/myapp.pfs file. When file doesn't exist, application crash down.
To vps I load finished container (docker save/load)
On localhost everything works file, after run docker compose up, from nginx-proxy folder, but on remote server, I got this:
docker-compose up --force-recreate cestujnakole

No such file in app means, cert file doesn't exist in remote pc
When i drop from remote machine folders to mount, after compose-up are created. It is very interesting.
Here is ls- l commnad on my remote structure:
ls -l
total 16
drwxrwxrwx 4 root root 4096 Jan 25 17:58 myapp
drwxr-xr-x 3 root root 4096 Jan 20 13:02 mysql
drwxr-xr-x 4 root root 4096 Jan 25 16:50 nginx-proxy
And nginx-proxy (my docker startup folder):
drwxrwxrwx 2 root root 4096 Jan 25 18:03 certs
-rw-r--r-- 1 root root 883 Jan 25 18:03 docker-compose.yml
I tested to nginx-proxy folder chmod -R and 775, after this 777, but nothing helped.
Where could the problem be?
Thank you for your time.
