As 15m FT8 here was dreadful here, I QSYed to 20m FT8.
Although I did a total reboot of the PC and reset the clock to internet time just now, still nothing on PSKreporter. Locally I am spotting loads of stations.
I wonder if there is a problem, albeit probably temporary, with PSKreporter? My RX and TX spots were fine on 2m FT8 earlier. I am pretty sure the internet connection is fine as I was able to do a time sync.
UPDATE 1506z: 1 spot on TX and 41 on RX now, so all is now fine.
