Hi! I have 6 RUTX11's total, and right now 4 of them are not connecting with the same error "failed to resolve hostname." The other two are working, and all of our sim cards from verizon and t-mobile are under the same plan and I've already troubleshot with them to make sure everything was in working order there. Two of the routers had been having hiccups the past few days, connecting and then not working again until we did a reset with the pin. Then yesterday, they completely would not connect, I tried to replace them with two new RUTX11s but we had the same issue, and I tried using two new sim cards as well with the same issue. When I log in to the router, it looks like everything is working except I get the error "failed to resolve hostname." Can anyone help me out with why this might be happening to certain routers and not others, and how to fix? Thank you!
