Blocking my Particle Photon

1

Hello, I am using your app on a Photon since 2-3 weeks without any problems.

Yesterday I created a share with a friend to show your great product.
After 1 hour circa my code in Particle (probably) lost the contact with the Cloud (Particle cloud) and also all possibility to function properly. My Photon kept breathing green.

Usually I get this if I have a bug in my code.

I disabled any calls made to Blynk and resolved the problem. :frowning:

Any way to figure out what happen here?

I am disappointed because I just love your app.

Let me know what we could do.

Thank you

Could you show your code?

The Particle make the connection for 10 seconds breathing light blue and then turn in breathing green.
When eliminating all relations with Blynk all is fine.
The following code ran for 2 weeks error free till I made the share from my phone.

Following is the code in Photon:

I probably found the problem. My Auth token in the Project settings is not the same as the one I programmed and worked for weeks.
How is this possible. I just made a share, how come the Auth Token changed???

If someone can explain this?

Probably @Dmitriy should look at this

@jmjobin there is only 1 explanation. You refreshed it.

It could well be.
I am sometimes lost to find the page settings page.
I found the navigation from the Blynk page and my running project not enough different and sometimes click around lost to try to find either adding icons or adding projects.
I probably click too much stuff. This would explain the problem.
About my code? Is something wrong? Why doing a wrong token place my Photon to green breathing?
