Hello! How are you? I hope you are doing well 
I am trying to use the odbc package to connect to a ms sql server data base for my application. When I run it locally, for example, on Rstudio, it does work just fine but when I try to run it on shinyproxy, or in a container directly, it doesnt work.
Here is the dockerfile
FROM openanalytics/r-base
#update all packages
RUN apt-get update
#upgrade
RUN apt-get upgrade -y
#install additional packages
RUN apt install gpg-agent -y unixodbc apt-utils curl unixodbc-dev \
sudo \
pandoc \
pandoc-citeproc \
libcurl4-gnutls-dev \
libcairo2-dev \
libxt-dev \
libssl-dev \
libssh2-1-dev \
libssl1.1 \
libmpfr-dev \
libxml2-dev
# R packages
RUN R -e "install.packages(c('shiny', 'rmarkdown'), repos='https://cloud.r-project.org/')"
RUN R -e "install.packages('Rmpfr', repos='https://cloud.r-project.org/')"
RUN R -e "install.packages('shinydashboard', repos='https://cloud.r-project.org/')"
RUN R -e "install.packages('xml2')"
RUN R -e "install.packages('rvest')"
RUN R -e "install.packages('plotly', repos='https://cloud.r-project.org/')"
RUN R -e "install.packages('reactable', repos='https://cloud.r-project.org/')"
RUN R -e "install.packages('tidyverse')"
RUN R -e "install.packages('DBI')"
#get msodbcsql17 and install it
RUN curl https://packages.microsoft.com/keys/microsoft.asc | apt-key add -
RUN curl https://packages.microsoft.com/config/ubuntu/20.04/prod.list > /etc/apt/sources.list.d/mssql-release.list
RUN apt-get update -y
RUN ACCEPT_EULA=Y apt-get install -y msodbcsql17
RUN ACCEPT_EULA=Y apt-get install -y mssql-tools
#install packaes needed for running the app
RUN R -e "install.packages(c('odbc', 'data.table'))"
# copy the app to the image
RUN mkdir /root/app_src
COPY app_src /root/app_src
COPY Rprofile.site /usr/lib/R/etc/
EXPOSE 3838
CMD ["R", "-e", "shiny::runApp('/root/app_src')"]
And here is the line where I connect to the data base
db_Inv <- DBI::dbConnect(odbc::odbc(), Driver = "ODBC Driver 17 for SQL Server", Server = "10.200.16.8", Database = "Investigacion", UID = "*****", PWD = "*****", Port = 1433)
As you can see, on the Dockerfile there are some lines about installing ms sql server drivers. I run the same lines on rstudio console and everything work just fine.
The problem when I run the code on shinyproxy or in the container directly is this:
Warning: Error in : nanodbc/nanodbc.cpp:1021: 00000: [Microsoft][ODBC Driver 17 for SQL Server]TCP Provider: Error code 0x2746 [Microsoft][ODBC Driver 17 for SQL Server]Client unable to establish connection [Microsoft][ODBC Driver 17 for SQL Server]Invalid connection string attribute

Do you have a guess?
Thanks!
