@SkyPi:Most likely you have claimed/linked your station using one email account, but when you visit web map, you login using another email.
Another possible cause may be that to visit web map, you are using station number which does not belong to you.
Please do this:
(1) Open file rbfeeder.ini to edit
sudo nano /etc/rbfeeder.ini
(2) In opened file check following line:
sn=EXTRPIxxxxxx
Is it EXTRPI010157 ?
If yes, go to step (3)
If no, then you have been visiting web map of a wrong site. Visit web map with station number in the file rbfeeder.ini
(3) In the file opened, add three lines shown in red below. Replace
xx.xxxx by your actual latitude value
yy.yyyy by your actual longitude value
zzz by your actual altitude value (meters above sea level)
[client]
network_mode=true
log_file=/var/log/rbfeeder.log
key=xxxxxxxxxxxxxx
sn=EXTRPI010157
lat=xx.xxxx
lon=yy.yyyy
alt=zzz
[network]
mode=beast
external_port=30005
external_host=127.0.0.1
[mlat]
autostart_mlat=true
#mlat_cmd=/usr/bin/python3.5 /usr/bin/mlat-client
[dump978]
#dump978_enabled=true
(4) Save file (Ctrl+O) and close it (Ctrl+x)
(5) Restart rbfeeder
sudo systemctl restart rbfeeder
(6) Wait 10 minutes, then check your map
