I click "Upload" and it appears to complete successfully (the status bar fills up and it lets me click "Finished") but nothing appears on LoTW even after a few hours (nor is there any record there of a file uploaded).
I'm using HRD v5.0 build 2893 and TQSL v1.3. I've double-checked username, password, and private password. I have also verified that my firewall allows HRD to reach the Internet.
Has anybody else had this problem?
