Networking Issues in Sequoia
We don’t recommend upgrading [to Sequoia] now because there are several bugs related to networking and firewalls in the 15.0 release. We expect most of them to be fixed in 15.1.

There are individual reports of websites aborting loading midway. We believe this is a general problem with TCP connections, not only
ssh, butsshseems to trigger it most frequently.[…]
If you have configured Apple’s firewall to block incoming connections, it blocks all incoming UDP packets, even if they are responses to requests, e.g. responses to DNS name lookups.
According to our tests, the issue with the built-in firewall appears to be fixed [in 15.0.1].

Recent user feedback indicates a shift of the situation: users who consistently encountered the problem no longer report it, while others, who were previously unaffected, are now experiencing
sshconnections dropping after some time. We don’t yet have sufficient data to determine whether this is coincidence or if the bug persists.[…]
We have received several reports from users of Little Snitch and Little Snitch Mini where the network content filter became inactive in the course of installing the macOS update. You’ll notice that you are affected if the Network Monitor stops displaying traffic or if connection blocking no longer works.

- macOS 15.0.1

I am using Windows App (previously called Microsoft Remote Desktop Client) with 15.0.1. After a few days of changing settings and seeing what happens, I believe that having any network filter enabled -- including Little Snitch and Trip Mode -- causes Windows App to drop the RDC connection periodically. Turning off network filters seems to have fixed the problem, knock-on-wood. Of course I’d like to keep using Little Snitch.
Off Topic: new M4 macbook with 10 CPU cores and 10 GPU cores, 16Gb Ram and 512Gb storage. Russian geek claims it's a base model to come out in November 2024. Possibly nabbed from the factory in China.
