Okay, I haven’t dug much into this yet, just checking to see if I am the only one seeing this. But the past few days I noticed when at work, I could not connect to my instance from the mobile app, claiming a problem with the SSH certificate. I am then connected to the wifi network ‘eduroam’, which is available at education and research institutes worldwide. I can connect when using my mobile data or from my laptop which connects to a different wifi network.
Anyone else experiencing this?
edit: forgot to add, I use Nabu Casa for remote connection, and I am on the latest version of HA (a few different beta versions over the course of the week and .0 release today)
Having worked four decades in .edu network administration, I’m sure that most schools treat eduroam connections the same as guest wifi on the network security side.
It would not surprise me if the school that you are at was using a firewall that is configured for strict packet inspection for SSL connections on their eduroam network, because I know that I would be if I was working for them. Unless this was working in the past and just broke, I would assume that it is a problem being caused by the local school’s eduroam restrictions and take the matter up with their IT support team…

A firewall should not mess with the SSL certificate, but a proxy might.
My guess is that a proxy is used for scanning the data and it acts as a man-in-the-middle attack, which the NabuCasa SSL certificate have protective feature for enabled.

It worked before. But IT policies change all the time and that is poorly communicated.
This sounds plausible. I will pass by the IT people office today or Monday. Maybe they can figure out how to avoid this.
Just a dumb question: do you have your time zones set correctly on all devices and showing the correct time?
Oh you will! Just like Richard Stoll in “The Cuckoo’s Egg”
Please keep us updated.
Yes, I have. That’s not it
