For months, I’ve been unable to get to the bottom of a networking issue that only seems to affect my newest Mac, an M2 MacBook Pro. Immediately after connecting to my home network, it is unable to connect to my Synology NAS server … until suddenly it is.
I often notice this because macOS can’t mount any SMB shares from the server, nor will Safari let me connect to its web UI. I’ll then head to the terminal to try to troubleshoot the issue. Here’s what that looks like:

I can’t tell if it’s something that I’m doing that’s “unblocking” the connection (in this case, connecting to it via SSH), or if it’s just a problem that self-corrects after a time.
My older, M1 MacBook Air and other devices (iPhone, iPad, etc.) seem unaffected.
It’s a strange quirk of modern computing that we don’t really have any place to go with home networking issues like this. If I contacted Apple support, they’d say they don’t support non-Apple network devices. If I contacted Synology support, they’d say they don’t support Apple computers.
I’d love to hear from anyone with an idea of where the problem might be!
