Web server not responding

[bgalport]

I'm having problems getting this fully working on my NodeMCU. I configured the unit via the web config page and from the serial log (below) it seems to be running (I can see IR messages on the console) but I cannot connect to the Web server using the the mDNS address or it's assigned IP of 192.168.10.38:667. I note from the log that the NTP request fails and that it does not respond to ping but I'm not sure if it should. The same device works fine on the local network with other code using the same (reserved) IP address. I saw the another issue reporting the same problem apparently related to static IP address usage but I'm using DHCP. Any suggestions?

Web related Library versions:

• ESP8266WebServer v1.0.0
• ESP8266Wifi v1.0.0

I hate the same issue. I can see the ESP connected to my access point but no response when trying to load the web page.

I had a similar problem. Try using the development version of WiFiManager. It's available on their GitHub page. This may be bacause the WiFi.config function now has DNS as the second argument instead of Gateway, as it was in earlier versions. But I could be totally wrong. Never the less, the development version of WiFiManager works for me.

I downloaded the WifiManager development version and deleted the one that the library manager installed first.

So far I have the board responding only on the first 5 seconds or so (I see serial log and entering on web interface) but after that time acts dead and I have to reset it. I tried disabling external IP querying and mDns services. It seems just hangs after a few seconds

It seems fixed, I had to force a full rebuild, I disabled mdns, querytime and query of the external ip as I will not use those, dont know if that helped, now its working fine (no hangs)

My webserver lasts 10-15 secs before it cannot be reached anymore. Cannot find out the reason for it, and none of the above helped

I had this exact symptom. First I thought that there were a problem with the webserver, I later noticed the entire NodeMCU was unresponsive, not just the webserver.

Make sure to set "Erase flash" to "All Flash Contents" if you're uploading it through the Arduino IDE. Also you could try the development version on WiFiMangager, it's available on their github page.

As I found 0.14 is the latest WifiManager and I already using it. Earsing the whole memory didn't helped either...
Also I set everything like yours, even the debug level 😅 No luck...

Not sure if this, but when I reinstalled ESP8266 core platform version 2.4.0 instead of the prev installed 2.5.2.... now it does not froze... however, still cannot receive signals. But that problem is for another day 😅

I have the same problem. Downgrading my ESP core to 1.4.2 does not change anything. I can not connect to the webserver......

Anyone figure out whats the problem?

[carranzafp]

Uninstall the wifimanager from the Arduino library manager and download manually the DEVELOPMENT version of WiFi manager (on the sketch folder it’s fine) then just rebuild

[hgghyxo]

What is helped me is found under the Board manager, not in the 'manage libraries' section

Guys, you are amazing.

I was also having problems with my Wemos D1 mini freezing and hanging after a few seconds.

Reducing the delay() in the loop() made it a little better no idea why...

Downgrading esp8266 platform to 2.4.0 has resolved the freezes! woohoo it's alive!

[morganchristiansson]

I have tried esp8266 platform 2.5.2, 2.4.2 and 2.4.1. 2.4.0 is the only one that doesn't hang.

edit: WiFiManager with esp8266 2.4.0 was getting stuck in configmode after reboot (even when configpin is not positive and false is passed to setupWiFi()). Using the development WiFiManager fixes it.

edit2: Also, WiFiManager dev branch does not resolve this ticket with esp8266-platform 2.5.2.

edit3: NTP is not working in 2.4.0 but is working in 2.5.2...

edit4: ntp is working now not sure why. Got it all working in the end even ntp. mDNS I've disabled tho got an exception when saving wifi config with it enabled. Not sure why I encountered so many issues the project is pretty straightforward, seems to be platform and libraries that caused these issues..

[gdgeist]

For me it turned out that the delay(200) in in the main loop appeared to be the issue. Not sure what the issue is that its blocking caused but removing that line ended all trouble.

Try the new dev branch Requires WiFiManager developer build from Github, not the one in the Arduino library
