Why I cannot connect to the Blynk server

Need Help With My Project
1

I cannot login to the Blynk，it told me that “Reconnecting to the server…”

Hello. Please try the latest app. What version do you have right now?

3

I am also facing the same issue since a week. I am using latest versions of Blynk library and Blynk app.

@rajindermath what error do you see? Android/iOS? Local/Cloud server?

It is with respect to Blynk cloud server. It says connecting to blynk-cloud.com:80 and never gets connected and shows login time-out. My projects were running smoothly I think a week ago. I am using latest Blynk library (0.5.2) latest version of Arduino IDE(1.8.5), latest Blynk app(2.20.3). Even for the given examples from sketch builder are not working. I tried using the older versions of Blynk library but didn’t work.

This how the BLYNK_DEBUG report looks like.

Moreover, the same sketch connects to Blynk cloud server when using my mobile hotspot but it doesn’t work with Wi-Fi. What might be the reason? A week ago there was no issues with the Wi-Fi connectivity to Blynk cloud.

8

Still searching for the solution. Is anybody facing the same issue here?

9

Actually in the latest Blynk library it should be port 80 and not 8442

10

Even if i provide 8442 in the sketch it redirects to Port 80. I even tried with port 80, but in vain.

11

I have the same problem…
connecting blynk-cloud:80 always timeout as result…
Please help to someone who has solution to this problem.

Because I couldn’t connect to the official Web server, I was in China and probably was banned, so according to the online tutorial, I created my own local server to solve this problem.
