If it makes a proper connection I don't know what is wrong. I wouldn't rush to erase the data. I'm sure Jachym will figure it out.

Yep. I did run the testupdate.php and see the following which may have some reason for this:
Update Test
Checking validity of data based on your limits in Main settings...
Checking date and time...
There seems to be a problem with the date and time. Either it has not been parsed correctly or it is a date/time in the future! Check the format you specified and also the actual values.
Minimum temperature allowed: -15 F
Maximum temperature allowed: 110 F
Temperature is outside the allowed limits! Temperature value will be ignored!
Minimum humidity allowed: 0 %
Maximum humidity allowed: 100 %
Humidity OK.
Minimum pressure allowed: 28 inhg
Maximum pressure allowed: 33 inhg
Pressure is outside the allowed limits! Pressure value will be ignored!
Minimum wind speed allowed: 0 mph
Maximum wind speed allowed: 200 mph
Wind speed OK.
Minimum wind gust allowed: 0 mph
Maximum wind gust allowed: 200 mph
Wind gust OK.
Minimum daily precipitation allowed: 0 in
Maximum daily precipitation allowed: 200 in
Daily precipitation OK.
Minimum rain rate allowed: 0 in/h
Maximum rain rate allowed: 500 in/h
Rain rate OK.
Minimum wind direction allowed: 0 degrees
Maximum wind direction allowed: 360 degrees
Wind direction OK.
Calculating dew point based on parsed values...
Temperature or humidity or both are not valid. Not possible to calculate dew point.
Calculating apparent temperature based on parsed values...
One or more parameters from the following: temperature, humidity, wind speed, are not valid. Impossible to calculate apparent temperature.
Summary
There is a problem with the date and time, nothing would be imported. Check the date/time format you specified and the actual values in the file.
