Getting error: (2026, 'SSL connection error: The message received was unexpected or badly formatted')

[madsmh]

When I ask Django to connect over SSL to a remote MariaDB, I get the above error, by database settings are:

`DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'USER': 'xx',
'HOST': 'xx',
'PASSWORD': 'xx',
'NAME': 'xx',
'PORT': '',
'OPTIONS': {'ssl': True},
}
}

furthermore, I have

MariaDB [(none)]> SHOW VARIABLES LIKE '%tls%';
+---------------+-------------------------+
| Variable_name | Value |
+---------------+-------------------------+
| tls_version | TLSv1.1,TLSv1.2,TLSv1.3 |
+---------------+-------------------------+

I have not been able to resolve this issue for some time, so any help is appreciated!

Your client may use too old OpenSSL. But I am not sure because you don't explain almost anything about your environment.

Sorry about that, let me post some details:
