Error in processing request Error code: 200. Error text: OK (rejected). It seems that the connection to server has been lost

Question

I added the following code to add a new server to phpMyAdmin:

$i++;
$cfg['Servers'][$i]['verbose'] = 'cat';
$cfg['Servers'][$i]['host'] = '129.111.21.444';
$cfg['Servers'][$i]['port'] = '';
$cfg['Servers'][$i]['socket'] = '';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['extension'] = 'mysqli';
//$cfg['Servers'][$i]['auth_type'] = 'cookie';
$cfg['Servers'][$i]['AllowNoPassword'] = false;

now, when I go to phpMyAdmin page, I see a drop down that I can use to connect to my desired server. After clicking the server name, I see a page where I should enter my user name and password. Once I do it, I can see the db on the left hand but I also see the following error:

Error in processing request
Error code: 200
Error text: OK (rejected)
It seems that the connection to server has been lost. Please check your network connectivity and server status.

When I try to click on the db, it gets me back to the log in page.

A screenshot of the error is also attached: I have updated phpMyAdmin as well, but, it did not help. Any other solution please?

Answer 1

I faced that problem and finally found the solution:
Go to Chrome settings -> Privacy & security -> Site settings -> Cookies & site data -> Allow it if blocked.
Enjoy it.

Answer 2

Adding https:// in front of the URL at the address bar works for me due to Chrome's security policy
