Network blocking UDP?
I use mosh (https://mosh.org/) to connect to some servers and have for years, which has normally worked fine, but for the last couple of weeks it has not worked over the tmobile network at all, the U...

For me they tried to blame Inseego.
To fix it, I had to drop down to 4G LTE.
I use discord and play video games over 5G; Voice in discord uses UPD, chat\text uses TCP. Everything that runs through TCP works fine, while everything that uses UPD does not work on 5G.
Anti-consumer basically. Got too big for their own good.
Please note that customer service is only there to follow a script; even they are unaware of what is going on with higher ups. The fact that you even know what UPD is means that you know more than 99% of their customer service.
For those of you that do not know; UPD is a network protocol that typically is used for low-latency applications that do not wait for a reply from the connected server. It is most commonly used for voice communications, online gaming in Real-time, pinging, or in Mosh's case; allows you to send packets without waiting on a packet to return; allowing it to appear latency-free. Compared to traditional where it seems really laggy because it is waiting on a reply from the remote service.
