@aaaron2030 this issue appears to be resolved. I love Bablosoft and I am very happy to see this working again.
Thank you
And even more interesting:
This is the response from the server (I changed my key of course):

What is the best way to get support from Bablosoft? I am really angry because they do not care.
I invested a lot of time and money in my project and they do not even try to help.
It started now working again.
I did not receive any helpfull message from Bablosoft. Also not a simple "Please check again it should now work again".
You can see it took about 70 minutes in this example I had running by the time.

@Grassman
Good afternoon, sorry for the late reply, today is Saturday(therefore, you received a late reply, sorry). Is everything working for you now?
I have attached the result below; the fingerprints are taken from the server.

Ok thank you for your help. It is working now.

I also encountered the same case.

I can not see any problem on your screenshot.
