Hi @RealNegril 

I'm currently dealing with exactly this same issue.


My site works on desktop browsers, but on mobile the browsers throw this same error.




I will update here if I find a fix.


Good luck!

My fix was to contact godaddy support through the chat function. 


I had godaddy reinstall the ssl cert on their end, and within minutes the issue was resolved.


PJ at the godaddy customer service was great and got me up and running.


Sorry I don't have better details on how to resolve this for you.. best of luck!
