I have been trying to install the dashboard since last week and continue to get the error message:
"Your server had a problem connecting to WPMU DEV: "GnuTLS recv error (-9): A TLS packet with unexpected length was received. Please try again."
My service provider assures me that curl is activated and sent me the following answer:
"Sorry but that error comes from the php code not from the server. You'd have to check with the programmer of the code why it isn't working."
I have tried to solve the problem by adding the following code to the wp-config.php file:
define( 'WPMUDEV_CUSTOM_API_SERVER', 'https://premium.wpmudev.org/' );
Unfortunately this doesn't work!
Please help me to connect the dashboard
