Do you mean you’ve opened up the firewall on the client PC?
You need to open up the firewall to the server pc.
I’m not sure what your server is on, but see if you’ve missed anything in one of these guides:
windows: Windows
ubuntu: Ubuntu
mac osx: Mac
If you’ve followed that, then try logging into manager on the server computer itself and see if you can access the server in a local browser (this will ensure your server is working locally, and will likely point to a firewall issue).
If you’re still having problems after that, be a bit more specific about your network:
- What is the server installed on?
- Is the windows PC on the same internal network and same subnet?
- Are you trying to access this via the internet and/or are there any other firewalls you haven’t considered?
