ESP32 Forum

With code that worked many times before, I am suddenly starting to get consistent update errors on *multiple* devices.
Any ideas why ?
Replaced the bin with a fresh one in case of corruption, uploaded manually to ensure the compile is good.

If OTA update fails, first step is to check for error messages that may be shown in upload window of Arduino IDE mcdvoice.

The plot thickens.
I'm pulling the bin file from raw.githubusercontent.com.
This worked perfectly well few months.
Suddently, earlier this week it stopped without code changes on my end.

Getting HTTP_UPDATE_FAILD Error (-1): HTTP error: connection refusedHTTP_UPDATE_NO_UPDATES.

Anonymous browser will download the file as before.

Trying to "debug" it a bit, looked into HTTPUpdate.cpp.
the first function where things don't work as they should is

bool HTTPUpdate::runUpdate(Stream &in, uint32_t size, String md5, int command)

the very first check (!begin) is already failing and returning error.

if (!Update.begin(size, command, _ledPin, _ledOn))


Any Ideas ?

yeah after resolving the error it will begin
