Thanks. My mistake was trying to use twt.social for the pod name.
No problem! Twt.social is our crappy attempt at “branding” and the 1-click fully managed hosted platform for those that either a) don’t know how to host/run thee backend and/or b) can’t be bothered. To date my pod (twtxt.net) is the largest and most active, but there are ~7 others we host on behalf of others at https://twt.social/join as well as two others which are completely independently run at twt.u53.net and txt.sour.is
