This issue is already quite widely publicized and quite frankly “we’re handling it and removing this” is a much more harmful response than I would hope to see. Especially as the admins of that instance have not yet upgraded the frontend version to apply the urgent fix.
It’s not like this was a confidential bug fix, this is a zero day being actively exploited. Please be more cooperative and open regarding these issues in your own administration if you’re hosting an instance. 🙏
You could try using a VPN or some other kind of proxy which wraps your SSH traffic to prevent packet inspection. Then it should look like normal UDP traffic ;)
They block UDP traffic too. I tried some things like that.
