Confirmed the 3 html files are present in .../Documents\AivlaSoft\EFB2\Server\Downloads

 

Current UTC is July 5, 2018 @ 0625.  There are several Eastbound NATs valid at this time so they should be appearing.

Have completely uninstalled and then reinstalled EFB2 with same results.

 

Running
Windows 10 64-bit
P3Dv4.3
Windows Defender AV

EFBv2
Server=2.0.52.0
Client=2.0.70.0

Yes, I can confirm the same issue here. I have however run Server Build #52 already yesterday and no such warning appeared. We have to wait until investigating further. It has happened in the past already a few times that the  NAT track server had a "hickup" delivering wrong data for some period. The last valid NAT track download I received with Build #52 was 5th of July, at 00:55.

We found the reason: for no apparent reason the NAT tracks were issued twice today! We will nevertheless introduce countermeasures for that. Who knows how many times this can and will happen (I've never seen that before though). This issue will be addressed with the next update.

How many time a day did you think NATS were issued?

 

Typically, the time of publication of the daytime (westbound) OTS is 2200 UTC and of the night-time (eastbound) OTS is 1400 UTC.

Oh come on, we are aware of that! They were issueing twice the same tracks!! (allow me to write this a bit bigger and more emphasized...) We may be stupid, but not THAT stupid!

 

Edit: Ok, I can reduce the fontsize again. The impact created was as expected...?
