Hello guys,
I have a weird issue with Plex player on iPhone. In local and remote mode, the server is shown as offline. When i use the Plex player on my laptop Windows 10 no issue connecting local and remote. I have an iPhone X and a friend with iPhone 7 IOS 11 has the same issue.
The port 80 is open on my router, and it can be accessed without any issue on any browser and the server is shown as connected.

Thanks for the help,
