After correctly following the instructions for creating a supported GroupWise environment for GW Web found here, and pulling the needed components to run the GW Web Docker image, you are unable to connect to the GW Web page with any browser after the docker run command completes without errors.
1. Browse to the location of the web.conf file on the server (you specified its location while using the web-config utility)
2. Open the file with a text editor
3. You should find there are spaces in the name of the Domain and/or Post Office. Replace those spaces with underscores, then save the file.
4. Restart the Docker GW Web by running the following commands:
docker stop gwweb
docker run -d -v:/etc/nginx/gw --name gwweb --rm -e FQDN= -e DNS_SERVER= -p 80:80 -p 443:443 -v :/certs mfgroupwise/web:latest
Spaces in the Domain or Post office name translate to invalid characters in the web.conf. A list of illegal characters can be found in the documentation
