I have multiple things running through a reverse proxy and I've never had trouble accessing them until now. The two hospitals are part of the same company, so their network setup is probably identical.
Curiously, it's not that the sites can't be found, but instead my browser complains that it's not secure.
So I don't think it's a DNS problem, but I wonder what the hospital is doing to the data.
All I could come up with in my research is this article about various methods of intercepting traffic. https://blog.cloudflare.com/performing-preventing-ssl-stripping-a-plain-english-primer/
Since my domain name is one that requires https (.app), the browser doesn't allow me to bypass the warning.
Is this just some sort of super strict security rules at the hospital? I doubt they're doing anything malicious, but it makes me wonder.
Thanks!
Also, if you know of any good networking Lemmy communities, feel free to share them.
The network is blocking your domain but your browser won't show the block page because the certificate is incorrect.
I've had my domain blocked by a few corporate networks for being "potential spam" or some such nonsense.
A redirect would work. This is not a redirect, it's TLS hijacking. Someone's injecting a bad certificate into OP's connections.
