sporadic error new QSO

[EA3GCV]

Hi Roland,

Thank you for the detailed explanation. It's all very weird... Any user has reported me something similar and myself I use Swisslog every day with JTDX with no issues. I think I got a similar error once some time ago and I had to restart Swisslog. But I got it only once. If you have added the exceptions to Swisslog and WSJT-X either in your antivirus and firewall then I don't know which could be the reason. All users I know use WSJT-X, JTDX or MhSV not WSJT-Z. However the UDP protocol used by WSJT-Z should be the same as WSJT-X. I guess it has nothing to do with the QRZ lookup but the UDP communication. The only way to know the source of this error would be to disable the QRZ lookup and see if you get this error again. Or use WSJT-X or JTDX dome days to see if this happen.

Please let me know if you find out something which can drive me to solve this sporadic and weird case.
