tried that, and already saw this link… followed it to even connect the esp in the first place.
ok I don’t know what I did but it’s working now… 
but I get invalid auth token… what is that?
Means the token in your sketch doesn’t match the one on the server.
This could be a simple cut and paste error, a geo-dns issue or you logging in to the wrong account on the server.
I am guessing you are using Blynk’s cloud server.
With the token in your sketch enter the following in a browser but change HERE for the token:
http://blynk-cloud.com/HERE/project
Does it give you some json data or nothing?
wait I’m running a local server… do I need to change anything in the sketch?
add the local server?
If you haven’t already done it in the app at login screen look for the router / traffic light icon, click it and move the slider from default (cloud) and enter your local server IP.
In the sketch change this:
Blynk.begin(auth, ssid, pass);
to this:
Blynk.begin(auth, ssid, pass, "xxx.xxx.xxx.xxx"); // xxx is your local IP
yeah I know that… I meant on the sketch… I’ll try something…
Edited my last post to include the sketch mod.
yeah figured it out but it won’t connect… says connecting to XXX.XXX.XXX.XXX and then repeats…
what port should I open in the windows firewall for this?
Ok same as before:
http://xxx.xxx.xxx.xxx/HERE/project in a browser where xxx is your local IP and HERE is your token.
If you don’t see the json data you probably didn’t set up the local server correctly.
WORKING!
not sure what I did… but now it’s working…
The only think I know I needed to do was to open 8442 port in the windows firewall and now it’s working.
THANK YOU @Costas for helping me figure everything out!
