ESP32+GSM .. Connecting to blynk.cloud:80 Login timeout

Abdo_Yasser · September 10, 2023, 6:46am

Hi … i’m new in the community from EGYPT .
but i have a problem with blynk server connection

it was working fine for along days , and yesterday i finally purches a pro plan for a month after many sucssfull work with blink .
but after yesterday subscribtion i have a " Connecting to blynk.cloud:80 Login timeout " error
without any change with hardware (ESP32 Wroom + SIM800L ) .

And for this error i return to the basic examble code for TinyGSM_SIM800_SIM900

I was working with 1.3.0 blynk library with arduino 2.2.1 IDE without any problem , but after ubove problem i upgraded the blynk library to 1.3.2 … but it not solve it .

pic from my blynk device dashboard

any help … ?
thanks

please edit your post, using the pencil icon at the bottom, and add triple backticks at the beginning and end of your code and serial monitor output so that it displays correctly. Triple backticks look like this: ```

Abdo_Yasser · September 10, 2023, 9:17am

thanks @Madhukesh

i edited it as you say .
can you expect what the reason of this server issues?

PeteKnight · September 10, 2023, 10:15am

It looks to me like you device can’t see the Blynk server.
Are you able to ping other websites via that hardware?

Pete.

Abdo_Yasser · September 10, 2023, 12:45pm

thanks @PeteKnight

How can i ping other websites via that hardware ??

PeteKnight · September 10, 2023, 4:34pm

Use a C++ Ping library, or an example that accesses an external server such as NTP example.

Pete.

Abdo_Yasser · September 12, 2023, 5:45am

Hi . i was trying to do any thing to connect to server but without any change .
I bought a new sim800l and also same problem .
I try to change sim card but without any change .

any help please

PeteKnight · September 12, 2023, 6:36am

What happens if you change this:

To something like this…

Blynk.begin(BLYNK_AUTH_TOKEN, modem, apn, user, pass, “lon1/blynk.cloud”, 8080);

You will need to replace “lon1” with the correct regional server for your project, which is shown in the bottom right hand corner of your web console.

Making this change has two effects:

ensuring that there are no DNS issues when trying to resolve the correct server
switching to port 8080 instead of port 80. This is often more successful, as many mobile ISPs block outbound traffic on port 80.

Pete.

Abdo_Yasser · September 12, 2023, 7:08am

thanks @PeteKnight

How can i check this ??

I put the regional server for my project as you say …

but unfortunately same problem

PeteKnight · September 12, 2023, 7:20am

You can’t.
As I explained, it’s a benefit of explicitly specifying the specific regional server.

But, I made a mistake when I told you how to specify the regional server. I’t should be this…

Blynk.begin(BLYNK_AUTH_TOKEN, modem, apn, user, pass, "ny3.blynk.cloud", 8080);

or

Blynk.begin(BLYNK_AUTH_TOKEN, modem, apn, user, pass, "https://ny3.blynk.cloud", 8080);

Try both and see what happens.

Pete.

Abdo_Yasser · September 12, 2023, 7:33am

Thanks @PeteKnight

I tried both but same issue

PeteKnight · September 12, 2023, 7:41am

When you said that you tried a different SIM, was this from a different provider?
Are these SIMs intended for IoT applications?

Pete.

Abdo_Yasser · September 12, 2023, 7:48am

Yes . I was working well with sim called " WE " with Orange EG provider as you see on terminal , but when this issue appear i tried a " Vodafone " sim … but without any change .

NO ,It is Not specified to the iot applications , but as i say i was working with " WE " which is a basic / normal sim and was working well .

PeteKnight · September 12, 2023, 8:18am

When you say “terminal” do you mean serial monitor?
If so, where have you posted serial monitor output that shows it working?

Pete.

Abdo_Yasser · September 12, 2023, 8:21am

Yes i’m sorry , i mean serial monitor .

this output

PeteKnight · September 12, 2023, 8:48am

Please don’t post screenshots of serial output.

That screenshot doesn’t show a successful connection.

Pete.
