Weird issue: some sites cannot be accessed when hooked to 4g LTE router

[hydrocynus]

Hello all, I bought a Tuoshi/dionlink 4g router which, once the firmware is updated open a lot of possibilities including ttl mod, band lock and more. I had it configured with visible/Verizon mvno and all was fine as I was not getting throttled and i could plug in several devices. All sites I accessed on the Internet loaded fine for a week. But I played with it and changed the ttl or especially locked it to some bands that Verizon uses in the towers around me.
I thought I had the best configuration as I was getting good speeds with the router but when I browsed the Internet, I found that some sites like Amazon would not open. When I enter amazon.com, then it takes a long time and nothing happens or I see the DNS error or www.amazon.com unexpectedly closed the connection.
ERR_CONNECTION_CLOSED.
Oddly enough, using a different browser than chrome like Firefox opens the site fine. But on either, I cannot open www.netzero.net where my email is.

I even reflashed the firmware but the issue still persists. Putting the sim card on my phone brings zero issues. Using the phone to share Internet via a gli.net router generates zero issues... But I am throttled.

I even used my other sim card with visible, different account, same issue.


So, I conclude it must be the router I pushed too far and now it has hardware issues?

Thanks for your help.

Oh and the issue happens on a PC or a tablet or a phone hooked up to the router.

Hello,
Sounds like you need to set costume DNS to the router.
