If the software can't download a config and there is a connection error in the logs saying:
'An attempt was made to access a socket in a way forbidden by its access permissions' it means another program is blocking access. The Microsoft help article here recommends taking the following steps.
1. Restart the windows firewall service
2. Reboot the problematic machine
3. Restart the “TCP/IP stack”. Run CMD as administrator, type “netsh int ip reset resetlog.txt” to reset TCP/IP.
4. Try to temporarily disable antivirus.
The most likely candidate is the Anti-virus.
