That is a firewall or router problem. Make sure you don't have Windows Firewall enabled (or change settings in it to allow mIRC full access). Also, make sure that Windows Defender is not blocking mIRC. Beyond that, if you have a router, make sure you have forwarded the port(s) that you are using for DCC.
