Hello All! I have a very strange issue with a customer for whom I set up a Blue Iris server at his home. When on a remote WiFi network (not his home WiFi), he can open his Blue Iris iOS app and connect flawlessly to view his cameras. If he turns off WiFi and uses his Verizon Wireless LTE, Blue Iris can't connect and gives the error "Check network availability". Back on WiFi, it again works flawlessly. So, in testing different scenarios we tried a few things. I had him download an iOS network tool and he can successfully ping his home router and can run a full, successful traceroute to it. Further, he can even visit his public ip: port in Safari and successfully pull up the login page for the Blue Iris web server. This problem has existed for a couple of months now and I'm out of ideas for what might be going on. Happy to provide any additional details if anyone has questions. Edit: forgot to add one important detail. I can dial in the same exact settings he's using (he's sent me screenshots) in to my iOS Blue Iris app on my phone and it connects flawlessly when I'm on AT&T LTE. Unfortunately, I don't have access to a Verizon phone to test it on that network.
