I am trying to test my site’s responsive design online and have tried over ten of the top tools (responsinator, responsivetesttool,ami. responsivedesign) an the site will not load onto any of them. They all say they cannot connect to the site.
Can you please advise on how to correct this? My site is live and I have had feedback it is not working well on tablet and mobile but I cannot test it properly t diagnose the issues.
