Hi, I have exactly the same problem, changing some line number:

Install moodle on external server "de novo" version 3.6.3 and after uploading external extensions try uploading SSL security certificate.

When I tried to change the configuration from http to https for the certificate to work, I get the error but I do not know how to correct it.

Attached screens of the result of uploading the SSL certificate to the moodle website that is correct. The result of the errors that appear is exposed in the first lines of the message

I do not know how to solve those mistakes.

Note: I have removed a "t" from the links of the errors (http or https) since when trying to send the message it considers it malicious.Thank you
