Guru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled about webota-esp32 HOT 5 CLOSED

Hi,

Please use the ESP32 exception decoder tool to give you more info about that error. https://github.com/me-no-dev/EspExceptionDecoder

Hi thank you for your reply. I will download the tool for debugging because it looks super useful, but finally after some time I have sorted it out.

I believe that the problem could be that I was connecting with "http://....." to my server but my server has https enabled with a certificate.

What I did was to use this example provided in the update library that is especially made for https. It is very important to format the certificate string as in the example with \n at the end of every line

To all people that get the error I got, if you have an https server use the example at this link

Hi @pedros89 , I had the same issue but solved it:
In my case, the HTTP response was 301: Moved Permanently. I think that this is caused by the .htaccess file on my webserver. It was configured (by WordPress) to replace the unencrypted http:// by the encrypted https://
In my case the solution was simple: modify my URL (as #defined in HOST) to include the s in https:// so that no redirect was needed. After the change, the HTTP response was 200: OK
An improvement for the code that is hosted here would be to either: only accept HTTP response 200 or (even better) follow the 301 redirect.
I hope this helps.

Will mark this issue as resolved

Hello @woutput, thank you for pointing that out. In my case because of that error I had abandoned this webota library, in addition I needed to have https, only http was not secure enough for my application.
I have developed a repository that allows you to update both ESP App and ESP spiffs and this is the one I am using at the moment. I am finding that the code based on the official ESP32 idf OTA is very reliable. Feel free to look at this repository:
