Quick question re TLSA lookup error

[Douglas Lucas]

Twitter keeps giving me "Twitter is over capacity. Please wait a few 
moments then try again" when I try to DM, so maybe there's a competent 
person on this list (lol) who can answer:


Under the Obama and Trump administrations, the US State Dept had a phone 
number for journalists to contact. It has since been removed; the 
website now instructs: email PAPressDuty at state.gov.

I looked up the old State Dept phone number and called it. The voice 
recording told me the same thing: email PAPressDuty at state.gov.

Monday I emailed.
Didn't get a reply until yesterday.

The reply I got was (among other error message stuff that appears 
general/unhelpful): "<PAPressDuty at state.gov>: TLSA lookup error for 
stimson.state.gov:25"

So I'm wondering if anyone can interpret the technical significance of 
such an error for me.


Predictable paint-by-numbers opinion blatherings by crazed and/or paid 
losers will be ignored.
