Thanks DebrodeD, that explain the timing since recently out wildecard certificate expired and I didn't renew it since we didn't need it anymore, or, well, I thought we didn't need it!In response to andre_x, apparently the new app doesn't allow using "self-signed certificates" which is what most of us use with Stunnel. Can anyone tell me the best solution to get mobile access to blue iris back up and running when away from home? This has been pretty low on my priority list since I've been working from home for the past year, but I'll be going back to work pretty soon and really want this working. From what I can tell the best options are either VPN or using a signed certificate? What is the easiest path forward?
About your need, use a VPN, Wireguard is pretty easy to setup and you can set it so that only the request to BLue Iris are forwarded, all the rest goes directly to the Internet.
You can install it on a RaspberryPI
