may https://pypi.org/project/emoji/ helps here. but no idea in which place in the code its needed. ```py >> import emoji >> print(emoji.emojize('Python is :thumbsup:', use_aliases=True)) Python is 👍 ```

can confirm this, looks like the core is getting bigger may some optimization has been changed. short fix use a atmega2560 board. first analyses with: ``` avr-nm --size-sort --print-size -r...

Hi, what ESP8266 core version do you use? the lines in you error message do not line up with the latest version: https://github.com/esp8266/Arduino/blob/master/libraries/ESP8266WiFi/src/WiFiClient.cpp#L261 may enable the build in debug messages...

Does that only happen with a SSL connection?

for platformio you need to set the defines in your platformio.ini something like this: ``` build_flags = -D DEBUG_ESP_PORT=Serial ``` but since its a SSL only problem its more likely...

the ``` state: 5 -> 2 ``` and ``` state: 5 -> 0 (1) ``` are WiFi state changes so you WiFi connection is instabile, its not a TCP or...

the error is coming from the SSL lib of the ESP8266 core (SSL_ALERT_HANDSHAKE_FAILURE) https://github.com/esp8266/Arduino/blob/eea9999dc5eaf464a432f77d5b65269f9baf198d/libraries/ESP8266WiFi/src/include/ssl.h#L138 hard to say what is wrong, but my bet is on TLS/SSL versions supported by cloudflare...

may this info helps https://github.com/home-assistant/core/issues/74539#issuecomment-1197721260

can confirm the lastest master still has this problem

some technical question, why does the `acme-http@internal` need the full `PathPrefix("/.well-known/acme-challenge/")`? I think a better solution for this problem is that traefik generates a specific rule for the ACME request...
