Problem with Internet Callsign Database

[f4bwj]

Hi, I'm Dom F4BWJ an happy user of Swisslog since I've return to radioham activities after a break of a few years.

Since yesteday I have a problem with Internet search via QRZ.com and HamQTH.com. Searching the datas when I type a new callsign in the Add QSO windows doesn't work anymore.
I get the message "Callsign doesn't exist" after "Getting QRZ session key" in despite it exist on QRZ.com or HamQTH.com.

However my user name and password are OK, for example search via QRZ.com is still working with VQLog.
 
I'm very disappointed as this internet search is very useful. I really don't know what could have happened as everything worked fine until tomorrow evening.

Is there something to reset or to look at to resolve the problem.
I've tried to refresh the database connection, after that I've completely reinstalled Swisslog 5.94 but the problem still remains the same. Something has failed after a Windows 10 update? I really don't know.

Am I the only one with this problem or some of you encounter this problem?

Many thanks in advance for your answers.
