I’m having the same problem. Everything that involves using a certificate isn’t functioning. HTTPS, Remote desktop, Azure/Bastion traffic, SSH with cert authentication, and more.
I’m not using Sentinel One; I found this place through a Google search. I’m on MS Defender here.
I’ll keep watching this.
This is likely a similar problem related to network filtering and how those applications work. Check if you have a filter, as I think MS Defender does as well (Settings → Network → Filters → Content Filter). If you can disable it, give that a shot.
For me, I couldn’t just turn off one specific filter, so I had to delete Sentinel One entirely, which is not what I wanted.
I found this thread through Google and can confirm that Sequoia and Defender alongside a network filter are causing lots of problems right now. I put Sequoia on my work Mac last week to test it and have seen various issues today like HTTPS websites timing out, not being able to control machines with ARD, and SSH file transfers failing with a message saying ‘ssh_dispatch_run_fatal: Connection to 10.2.1.233 port 22: Connection corrupted’. Turning off the Defender network filter seems to have fixed all these problems.
Honestly, I wasn’t even aware it was enabled. I set up Defender a while ago using the lengthy MS guide, and it must have been one of the steps. I have a JAMF config profile called ‘defender network extension’ which I might just disable since I really don’t want Defender affecting my network traffic.
Do you have Firewall turned on in Network → Firewall → Firewall by any chance?
I know I do and I’m starting to think that Defender and Sentinel One filters might be conflicting with it.
I’ll try disabling the Firewall (since it usually defaults to OFF on MacOS) and then reinstall Sentinel One to see if that helps.

Many people have reported issues if both MacOS Firewall and a network filter like Defender, Sentinel One, or others are running together. It seems more like a MacOS issue or bug at this point.
u/SentinelOne-Pascal FYI… This could be the root cause; I’ll test it out and let you know how it goes (including in my ticket with Sentinel One Support).

Looks like we aren’t alone here.
