I'm happy this thread exists - I noticed the problem after rebooting for an update and couldn't figure out why I could no longer connect. I was using a Linux box as a fileserver - but decided to move the drives to my Mac, so this didn't bite me until now.
I eventually realized that when shutting off the Firewall connections from clients could be made. I ended up finding an article on 6 colors about adding smbd to the firewall and making sure that it was not blocked using
Code:
/usr/libexec/ApplicationFirewall/socketfilterfw --listapps
But nothing helped. The tip on shutting off file sharing before rebooting is the only thing that really works(?) so far.
I'm wondering if it would be worth it to try something like Murus (
murus) to workaround this? I've been meaning to try it out since the built-in Firewall app is not very good.
Seems crazy something like this gets by QA - and does not get fixed right away by one of the wealthiest companies in the world. I wonder when this bug started - I feel like I found some search results about this issue going back to last year...
