Ctrader Connectivity issues (possibly due to 3g Router)?

Hi,

Starting this morning, I suddenly have an issue where I cannot log into Ctrader anymore. My net works perfectly fine for everything else, It just gives me the initial loading screen. I've been trying to fix it all day with no avail. I usually use an Android phone to log into the app which it initially failed on. I uninstalled/cleared cache, loaded the app on an iphone, tried the web browser from a mac/PC  but all those attempts failed https://speedtest.vet/ https://vidmate.bid/ https://wordtopdf.ltd/ and I kept getting a loading screen. When i switched  to our downstairs DSL modem and it suddenly worked and i could log into ctrader again.

p.s. I've also tried another 3g modem to test it out, and I got the same issue with it constantly loading/ failing to connect. I also didnt change anything from my side, it just suddenly stopped working.

Im actually stumped how to fix this issue. Kindly advise me
