[atlas] probe tagged as "system: Firewall problem suspected"

Hi Viktor,

The network looks good.
The last time I had a problem with my probe, the flash drive was the guilty one. So, as you suggested, I will reinit the flash drive and see how it goes. I will keep you updated.

Thanks for the hints!

Sarah

Hi Sarah,

The tagging is done by heuristic that analyzes the probe connection 
attempts, SOS, timing between them and some other attributes like 
messages about flash drive. It has to have a quite large window for 
looking into data and it can take up to a few days for addressing a 
probe to a special controller if needed and resetting tags.

In your case I see that it was disconnected at 2016-02-12 12:26:09. Up 
till this time your probe had no problem connecting regservers and 
controllers (tcp/443). After that time I see only SOS (DNS 
(tcp|udp)/53). That suggests the network problem with the highest 
probability - DNS is open but tcp/443 is closed. The lowest probability 
has the hardware problem (flash drive) in this case.

Please use the tag as a suggestion where to begin your local 
diagnostics. If the network is good you can try to reinit the flash drive.
