Client connections not closed when station is disconnected from soft AP

[iduquegit]

When a station connects to the soft AP and I'm serving files (with multiple connections open), if the WiFi connection is abruptly closed, those connections remain open, and the PsychicHttpServer::onClose() callback is never triggered.

Should I manually close those connections when the station disconnects, or is there a better approach to handle this?

I think this is somewhat related to my issue. I get a crash when a client vanishes and I want to send sse messages to it. Psychic does not correctly closing some sockets in some cases and I think it wants to send packets to nullpointers.
