Apache error log

Hi guys,

After installing Let’s Encrypt SSL only on my HOSTNAME (my sites have their own SSL certificates), my sites open slowly and i found these errors in apache error log:

Code:

[Mon Feb 20 03:31:02.001783 2017] [ssl:warn] [pid 17251:tid 132253987817600] AH01909: localhost:443:0 server certificate does NOT include an ID which matches the server name

any help will be appreciated.

Best regards,
Sergey
