Original GitHub issue: https://github.com/tzapu/WiFiManager/issues/1037

i have an problem to get my sketch working with my esp. I cannot make an connection with the server apparantly, and it will not return messages thus.
(https://www.youtube.com/watch?v=k4Ux_I4Gl30&t=11s)
I tried almost everything a newby could have done, so now i am reaching out , cause the wifimanager is not working, i believe?
i tried several hosts in the sketch, used http and https hostst, switched to other esp boards,placed a Serial.setDebugOutput(true)in the sketch to find out what might have been the issue. For now i have a connection with the router i believe cause it gives me no' failure 'in the serial. (First i had a no connection failure all the time..)
when i try to obtain the message from the serverscript online , it failes, the script however reports the EOT , so the script is working. But the connection is not made to retrieve it ?
Could you please look into it and see if there is anything wrong? Any suggestions would be great :)

-router is seeing the esp, gives ip adress
-http or https domain not working (dailydeals.one/woodiebox/matrix)(lichtkrant.epizy.com/test)
-Oled states that is has a connection with wifi
-connected to the host outside my network (mobile)

i use a NodeMcu Lua CH340G (nodeMcu 1.0 esp 12e module setting) with two matrix led max7219
esp3266 addon 2.6.0 and downgraded it also to 2.4.0 (same results)
4-1 module and a 7 pin oled 1.3 inch display.
wifimanager version 0.15 used , but also tried 0.14 version

CODE:

void ConnectToServer(){
  // Use WiFiClient class to create TCP connections
  const char* host      = "dailydeals.one";                 // Here coms your Webserver / Host adress
  String url       = "/woodiebox/matrix/myText.txt";         // The Path and Filename
  WiFiClient client;
  const int httpPort = 80;
  if (!client.connect(host, httpPort)) {
    Serial.println("connection failed");
    return;
  }   
  // This will send the request to the server
  client.print(String("GET ") + url + " HTTP/1.1\r\n" +
               "Host: " + host + "\r\n" + 
               "Connection: close\r\n\r\n");
  unsigned long timeout = millis();
  while (client.available() == 0) {
    if (millis() - timeout > 5000) {
      Serial.println(">>> Client Timeout !");
      client.stop();
      return;
    }
  }
  // Read all the lines of the reply from server
  while(client.available()){
    String line = client.readStringUntil('\r');

    if(line.endsWith("EOT")){                         // line with EOT at the end? (adding in PHP-Script to the end of text)
      line = line.substring(1,line.length() -3);      // Shortens the string by by 3 characters "EOT"

I do not see anything from ConnectToServer in your serial log

Serial.println("connection failed");
  Serial.println(">>> Client Timeout !");

add some debugging your your client code.. shrug try something easier like get ntp time or something

No , well thats the point, i can not connect to the server! I had a serial print line connection failed, that vanished as soon as i upgraded my board to 2.6.3 version. The designer of the sketch had a serverscript that was placed on a NAS , does that change anything within my code do you think?
Still, i can not figure out how i can get my connection to the server .
since it does not say connection failed or time out for client , i pressume it has a connection , but it can not retrieve the info i want...
Debugging client code you say, how is that done?
What does this : pm open,type:2 0 mean btw ? Do you know? Cant find it anywere .

thanks for your suggestions and help, i can't find the troublemaker that is causing this and any help i am gratefull for

Thats just low level wifi debugging.

Does the serial print(line)output anything?

You need to add more prints to see where its getting to

Still bugging around with the problem, i was trying to connect to the server URL from the designer. Guess what, it received the message i typed there. So when i placed the URL from the server from the designer into my sketch , it worked. I had my textmessage printed on my LED matrix.
Thuss, the code is OK. It still has something to do with connecting to my html page . maybe serverscript ?

Serial gives me no more info btw, it still keeps ending at pm open,type:2 0

For i know the only difference between me and the designers connection is that he posted his script on his NAS , and i mine on my external website server. But that could not make any difference does it?

Are you getting stuck in while(client.available()){ ?
does it ever exit?

I dont know, i use the same serverscript , so far i know, and with connection made to developers nas , no problems!!
But when i use the script on my own hosted sites (several) it does not return the messages , so logical , for me , it must mean that the server script was altered . In the code the while(client.available()){ must be right. I can connect with developers nas(site)..
My settings for the modem/router and multiple hosts i tried , were also correct.

I posted a request to the developers adress for serverscript comparances. I am breaking my head on this issue for a month or so now.
I dont want to piggyback on his server for my project to work , i need my own host to operate properly offcourse . i think i better wait for a response to see if the script was altered or not ..

Could be the way the server returns whitespace readline until \r

Like I said you need to dump debug logs from your micro to see what data is coming, and use a static file to fetch data from for testing

Solved!

I used another free webhosting , made a account to upload my script and it worked. Probarly on my own sites the software that runs the site blocked the script. Anyway, thanks for your input , you've been helpfull 👍
