1 year ago modifying the bool initWifi() function by assigning the primary DNS in WIFI.config prior to calling WIFI.begin the local time is now correct using static IP address, this also fixed Telegram notifications failure as the time stamp used cannot be before current time.
Adapter settings:
Code:
`
bool init_wifi()
{
int connAttempts = 0;
// *** NEW CODE - Assign Network Adapter Settings **
// Set static IP IPAddress local_IP(192, 168, 1, 142); // Set your Gateway IP address IPAddress gateway(192, 168, 1, 1); // Set your Gateway IP address IPAddress subnet(255, 255, 0, 0); // Set your primary DNS, required to get the correct local time IPAddress primaryDNS(192, 168, 1, 1);
//**

I added multiple ESP32 cameras to a webpage but found that certain ESP32 Cam IP addresses will not load in browser i.e., (192.168.1.108) so I assigned each ESPcam with a static IP address using the following code: `
now all the cameras load in HTML Iframes however this has affected other functionality.
All cameras live stream simultaneously, saving of images and video to SD works and is accessible in file manager.
However Telegram notifications stopped working and time stamp is incorrect. its showing out of sync time and year is 1970.
I'm trying to get a better understanding how the libraries work together mainly Telegram and assignment of local time and why having a static IP would stop notifications, any help would be appreciated.
