Tray again to upload QSO's to Lotw. Then Error occoured: Needs a password... But I have not set (never) a Password for none of the Certificates and I did this always. Last I uploaded is abt 28.October from TA3 - after one week from SV8 same Error, also now from HB9. (Have logs from HB9/TA3/SV8/EA8) Btw: My old QTH Adress still in the online Log. I changed the Adress to my new QTH in 2021 Autum. On the Info Page it's correct, but during LOG upload the import app changes to the old.
Logbook problems are best addressed in the Logbook User forum. The ARRL issued you a password when you set up LoTW. Perhaps you need to download a new certificate? What exactly is the error message? Go to Logbook Settings -> Logbook Properties and scroll down to QTH info for each of your logbooks. Correct as necessary and Save.
