HRDLOG window is black

[SP1JQJ]

Submission confirmation type: HRDLOG.
the green line goes forward but the window is black.
green reaches the end and HRDLOG END appears.
I go back to QSL Manager and the same thing happens again:
HRDLOG, Select required, same QSOs appear to be unsent, Resend... black box again.
It is always like that.
There is a QSO in HRD, but LOG4OM does not mark it as sent.

What does log file say?

After some time, the server was blocked.
I couldn't upgrade from the browser.
Now the server is open for the browser and LOG4OM.
Everything works.

Like I said in my other reply if this recurs go to help/show log and see what the reason is, probably will be marked as an 'Error'

OK
