Hi there,
As a sysadmin, i can help you sort it out for problem, can you show me what is going in on there? over teamviewer or the way you prefer, so i cna better understand your requierement.
if is somethign with the SSL certificate over your webserver (NGINX, Apache) perhaps something is missing on the .conf files, or perhaps your SSL hasnt been correctly installed or generated.
Let me know,
Sebastian
