First of all, ESET's firewall doesn't block any programs, only HIPS can. The firewall controls the network communication. By default, in automatic mode all outbound communication is allowed and all non-initiated inbound communication is blocked.
Please continue as follows:
- switch logging verbosity to diagnostic
- enable advanced network protection logging under tools -> diagnostics
- reboot the machine
- reproduce the issue
- stop logging
- collect logs with ESET Log Collector and upload the generated archive here
- provide information about the remote IP address whose communication with this machine was blocked.
