Server: Windows Server 2012, FileMaker Server 220.127.116.11
Client: iPhone 6s Plus, FileMaker Go 15.0.4, iOS 10.3.1, T-Mobile Service
I'm experiencing an issue where my FileMaker Go clients are unable to reach our host server when they are on LTE. This issue is only happening on iPhones that have been updated to 10.3.1 and are run on T-Mobile. When using wi-fi they are able to connect with no problems. All other functions of the phone work on LTE (e-mail, maps, etc.)
I've tested it on the following devices and everything works as expected:
iPhone 6s Plus, FileMaker Go 15.0.4, iOS 10.2.1, T-Mobile Service
iPhone 7 Plus, FileMaker Go 15.0.4, iOS 10.3.1, Verizon Service
iPhone 7, FileMaker Go 15.0.4, iOS 10.3.1, AT&T Service
Has anyone else experienced this or have any idea what could be the issue?
