Need help Wallet. there are no settings, there is no information

Is the situation that the above is accessible normally and can not be accessed from NanoWallet?

Yesterday worked, but today does not work anymore

From the browser I can see the URL above.
If you can not see the above, NanoWallet will not move.

From the fact that it was seen yesterday, it seems that the environment of PC and network is not stable.
Firstly we recommend restarting PC or network equipment.

It does not connect to any of the servers.
The circle is red.
What advise yet?

If you access the above from the browser and there is no reply, there is a problem with the network.
On the contrary, if you can access from the browser and can not access from NanoWallet, you can think of browser settings as problem.

To use NanoWallet, use port 7890 instead of port 80 normally used for http protocol.
For this reason, it is most likely that the communication you want to use is being blocked by the security software used on the PC and the FireWall function of the network equipment.

For this reason, it is extremely difficult to determine which is bad unless you actually check the network environment.
If neighbors and friends have someone who is familiar with the network, having it seen once will be a shortcut to solution.
