So i have 5 Formuler z7+ boxes connected to a Linksys 1900 acs router. I use a steaming service via M3U but for some reason, only 2 of the 5 tv's work. The other 3 get stuck on the initial loading page. I use express vpn and all formulers connect directly to that router. I tried changing the server location but that does not work. Only when i turn off the vpn will it load. Im not sure why i get an error message when its trying to load up. In addition, i tried to update the formuler to the latest version but couldn't (at the time) as it said something in the lines of "not connected to the internet" but when that happened, i did a speed test and it showed i was doing well beyond the required speed. The fact it gave me speed results means i was connected to the internet but the box would not boot up the player nor would it update anything until i turned off the vpn.
So itll work fine when i turn the vpn off, loads up and get picture, turn the vpn back on, still works fine but the next day after i power it down from the day before then power back it back on, it gets stuck on the loading screen until i do the mentioned steps again. Let me know if anyone has any suggestions as to why this is happening and how i can resolve this issue. Thanks in advance.
