ERR_SSL_PROTOCOL_ERROR when I click on landing page link



I've been getting new subscribers but yesterday I noticed that the link to the subscription landing page is not working. It gives an error that reads: 

This site can’t provide a secure connection sent an invalid response.


Kindly troubleshoot this problem because I believe it is on Constant Contact's end, I've done everything possible from my side to resolve the issue and nothing seems to help. 

Thank you. Hoping the link will be active soon!
