In my case, it was only happening in HTTP (HTTPS was ok), but I was needing HTTP for local use (without my domain https name). My config.php was like this:
‘trusted_domains’ =>
array (
0 => ‘192.168.1.170:8000’,
1 => ‘192.168.1.170:8443’,
2 => ‘mydomain.com:443’
And I solved it by removing repeated domain (with different port):
‘trusted_domains’ =>
array (
0 => ‘192.168.1.170’,
1 => ‘mydomain.com’
In fact, it seems that putting more than one domain with different port causes unexpected troubles, so it’s better to authorize the full domain without ports.
